It will take as input a set of normal modes calculated for an input atomic or pseudoatomic structure, and a set of volumes (subtomograms) to analyze. It fits the input structure using its modes (a subset of the modes need to be selected) into each one of the input volumes while simultaneously looking for rigid-body alignment, with compensation for missing wedge artefacts. The result of this protocol are rigid-body and elastic parameters for each input volume. Those results will be fed for a dimensionality reduction method (nma dimred vol) for further processing.

refine subtomogram alignment
- Protocol for refining subtomogram alignment and filling the missing wedge based on optical flow and Fast Rotational Matching (FRM). The protocol takes as input a set of subtomograms, with their subtomogram averaging protocol. It uses this global subtomogrm average to fill the missing wedge in Fourier space (the missing wedge is replaced by the corresponding region from the global average). Optical flow is used to match the global average with each of the missing wedge filled and aligned subtomograms (matched subtomograms are generated). Rigid-body alignment is performed using FRM from the matched subtomogram, and the rigid-body alignment for the input subtomograms is updated. Few iterations are usually sufficient (1-5), and the rigid-body alignment will be refined
-
structure mapping

Cryosparc2
Available in Linux.
Scientific software, Image processing, cryo em
Available methods:
-
2D classification (2D classification)
- Wrapper to CryoSparc 2D clustering program. Classify particles into multiple 2D classes to facilitate stack cleaning and removal of junk particles. Also useful as a sanity check to investigate particle quality.
-
3D Classification
- 3D Classification (BETA) is a new job in cryoSPARC v3.3+ to analyze discrete heterogeneity in single particle cryo-EM datasets. This job currently implements a version of 3D classification without alignment — a classification routine that can complement the existing Heterogeneous Refinement job in finding new discrete classes of data.
-
3D Heterogeneous Refinement (3D classification)
- Heterogeneous Refinement simultaneously classifies particles and refines structures from n initial structures, usually obtained following an Ab-Initio Reconstruction. This facilitates the ability to look for small differences between structures which may not be obvious at low resolutions, and also to re-classify particles to aid in sorting.
-
3D helical refinement
- Reconstruct and refine a homogeneous helical assembly, with or without imposition and refinement of symmetry parameters. Helical Refinement (BETA) uses an algorithm that is conceptually similar to Egelman's Iterative Helical Real Space Reconstruction (IHRSR) algorithm, while incorporating the same maximum likelihood framework, accelerated branch-and-bound alignment algorithm, and optional Non-Uniform regularization as used in other cryoSPARC refinement jobs.
-
3D homogeneous refinement
- Protocol to refine a 3D map using cryosparc. Rapidly refine a single homogeneous structure to high-resolution and validate using the gold-standard FSC. Using new faster GPU code, and support for higher-order aberration (beam tilt, spherical aberration, trefoil, tetrafoil) correction and per-particle defocus refinement on the fly.
-
3D homogeneous refinement(Legacy) (3D refinement)
- Protocol to refine a 3D map using cryosparc. Rapidly refine a single homogeneous structure to high-resolution and validate using the gold-standard FSC.
-
3D non-uniform refinement
- Apply non-uniform refinement to achieve higher resolution and map quality, especially for membrane proteins. Non-uniform refinement iteratively accounts for regions of a structure that have disordered or flexible density causing local loss of resolution. Accounting for these regions and dynamically estimating their locations can significantly improve resolution in other regions as well as overall map quality by impacting the alignment of particles and reducing the tendency for refinement algorithms to over-fit disordered regions.

-
ctf auto (CTF estimation)
- This protocol wraps *e2ctf_auto.py* EMAN2 program. It automates the CTF fitting and structure factor generation process.
-
initial model (Initial model)
- This protocol wraps *e2initialmodel.py* EMAN2 program. It will take a set of class-averages/projections and build a set of 3-D models suitable for use as initial models in single particle reconstruction. The output set is theoretically sorted in order of quality (best one is numbered 1), though it's best to look at the other answers as well. See more details in: http://blake.bcm.edu/emanwiki/EMAN2/Programs/e2initialmodel
-
initial model SGD (Initial model)
- This protocol wraps *e2initialmodel_sgd.py* EMAN2 program. This program makes initial models using a (kind of) stochastic gradient descent approach. It is recommended that the box size of particles is around 100.
-
reconstruct (3D reconstruction)
- This protocol wraps *e2make3d.py* EMAN2 program. Reconstructs 3D volumes using a set of 2D images. Euler angles are extracted from the 2D image headers and symmetry is imposed. Several reconstruction methods are available. The fourier method is the default and recommended reconstructor.
-
refine 2D (2D classification)
- This protocol wraps *e2refine2d.py* EMAN2 program. This program is used to produce reference-free class averages from a population of mixed, unaligned particle images. These averages can be used to generate initial models or assess the structural variability of the data. They are not normally themselves used as part of the single particle reconstruction refinement process, which uses the raw particles in a reference-based classification approach. However, with a good structure, projections of the final 3-D model should be consistent with the results of this reference-free analysis. This program uses a fully automated iterative alignment/MSA approach. You should normally target a minimum of 10-20 particles per class-average, though more is fine. Default parameters should give a good start, but are likely not optimal for any given system. Note that it does have the --parallel option, but a few steps of the iterative process are not parallellised, so don't be surprised if multiple cores are not always active.
-
refine 2D bispec (2D classification)
- This protocol wraps *e2refine2d_bispec.py* EMAN2 program. This program is used to produce reference-free class averages from a population of mixed, unaligned particle images. These averages can be used to generate initial models or assess the structural variability of the data. They are not normally themselves used as part of the single particle reconstruction refinement process, which uses the raw particles in a reference-based classification approach. However, with a good structure, projections of the final 3-D model should be consistent with the results of this reference-free analysis. This variant of the program uses rotational/translational invariants derived from the bispectrum of each particle.
-
refine easy (3D refinement)
- This protocol wraps *e2refine_easy.py* EMAN2 program.This is the primary single particle refinement program in EMAN2.1+.It replaces earlier programs such as e2refine.py and e2refine_evenodd.py.Major features of this program: * While a range of command-line options still exist. You should not normally specify more than a few basic requirements. The rest will be auto-selected for you. * This program will split your data in half and automatically refine the halves independently to produce a gold standard resolution curve for every step in the refinement. * An HTML report file will be generated as this program runs, telling you exactly what it decided to do and why, as well as giving information about runtime, etc while the job is still running. * The gold standard FSC also permits us to automatically filter the structure at each refinement step. The resolution you specify is a target, NOT the filter resolution.
-

deconvolution Loo-Riegelman
- Calculate the absorption profile of an in vivo concentration profile using the Loo-Riegelman approach. This is only valid for profiles that have been modelled with a two-compartments PK model. The formula is Fabs(t)=(Cp(t)+Cperipheral(t)+K10*AUC0t(t))/(K10*AUC0inf) where K10=Cl/V and Cperipheral(t_n)=k12*Delta Cp*Delta t/2+k12/k21 * Cp(t_n-1)(1-exp(-k21*Delta t))+Cperipheral(t_n-1)*exp(-k21*Delta t) In this implementation it is assumed that AUC0inf is the last AUC0t observed, meaning that Cp(t) has almost vanished in the last samples. This protocol is much more accurate when the input Cp(t) is reinterpolated to a small time step like 0.5 minutes. Reference: Leon Shargel, Susanna Wu-Pong, Andrew B.C. Yu.

On the other side, it has the disadvantage of considering the noise as true fluctuations due to the absorption.

The differential equation is V dC/dt = -(Clint+Clp) * C + Clp * Cp + dD/dt, Vp dCp/dt = Clp * C - Clp * Cp and Clint=Vmax/(Km+C) where C is the concentration of the central compartment, Cl the clearance, V and Vp the distribution volume of the central and peripheral compartment, Clp is the distribution rate between the central and the peripheral compartments, Vmax is the maximum processing capability of the metabolic pathway degrading the drug, Km is the Michaelis-Menten constant,and D the input dosing regime. Note that the intrinsic clearance occurs at the central volume. Confidence intervals calculated by this fitting may be pessimistic because it assumes that all model parameters are independent, which are not. Use Bootstrap estimates instead.

-
3D multi-body (3D refinement)
- Relion protocol for multi-body refinement. This approach models flexible complexes as a user-defined number of rigid bodies that move independently of each other. Using separate focused refinements with iteratively improved partial signal subtraction, improved reconstructions are generated for each of the defined bodies. Moreover, using PCA on the relative orientations of the bodies over all particle images in the data set, we generate movies that describe the most important motions in the data.

-
auto-picking LoG (Particle picking)
- This Relion protocol uses 'relion_autopick' program for the Laplacian of Gaussian (LoG) option.

bayesian polishing
- Wrapper protocol for the Relion's Bayesian Polishing. As of release 3.0, Relion also implements a new Bayesian approach to beam induced motion correction. This approach aims to optimise a regularised likelihood, which allows us to associate with each hypothetical set of particle trajectories a prior likelihood that favors spatially coherent and temporally smooth motion without imposing any hard constraints. The smoothness prior term requires three parameters that describe the statistics of the observed motion. To estimate the prior that yields the best motion tracks for this particular dataset, we can first run the program in 'training mode'. Once the estimates have been obtained, one can then run the program again to fit tracks for the motion of all particles in the data set and to produce adequately weighted averages of the aligned movie frames.

-
align pairwise (2D alignment)
- This protocol wraps SPIDER AP SR command (pairwise alignment). Reference-free alignment (both translational and rotational) of an image series. This alignment scheme aligns a pair of images at a time and then averages them. Then, the averages of each of those pairs are aligned and averaged, and then pairs of those pairs, etc. Compared to [[http://spider.wadsworth.org/spider_doc/spider/docs/man/apsr.html][AP SR]], this alignment scheme appears to be less random, which chooses seed images as alignment references. For more information, see Step 2b at [[http://spider.wadsworth.org/spider_doc/spider/docs/techs/MSA/index.html#pairwise][SPIDER's MDA online manual]]
-
ca pca (2D classification)
- Protocol for Correspondence Analysis (CA) or Principal Component Analysis (PCA). CA is the preferred method of finding inter-image variations. PCA computes the distance between data vectors with Euclidean distances, while CA uses Chi-squared distance. CA is superior because it ignores differences in exposure between images, eliminating the need to rescale between images. In contrast, PCA seems to be more robust: less likely to be trapped in an infinite loop of numerical inaccuracy. For more info see: [[http://spider.wadsworth.org/spider_doc/spider/docs/techs/classification/tutorial.html#CAPCA][SPIDER MDA documentation]]

- This protocol wraps SPIDER CL HC command. Finds clusters of images/elements in factor space (or a selected subspace) by using Diday's method of moving centers, and applies hierarchical ascendant classification (HAC) (using Ward's method) to the resulting cluster centers.
-
create 2d mask (Masking)
- This protocol creates a 2D mask using SPIDER. In the step following this one, dimension-reduction, the covariance of the pixels in all images will be computed. Only pixels under a given mask will be analyzed. If this step is performed, a mask that follows closely the contour the particle of interest will be used. Absent a custom-made mask, a circular mask will be used. For non-globular structures, this customized mask will reduce computational demand and the likelihood of numerical inaccuracy in the next dimension-reduction step. On the other hand, given the power of modern computers, this step may be unnecessary.
-
filter particles
- Apply Fourier filters to an image or a volume using Spider FQ or FQ NP. To improve boundary quality the image is padded with the average value to twice the original size during filtration if padding is selected. See more documentation at: [[http://spider.wadsworth.org/spider_doc/spider/docs/man/fq.html][SPIDER's FQ online manual]]

-
refine 3D (3D refinement)
- Reference-based refinement using SPIDER AP SHC and AP REF commands. Iterative refinement improves the accuracy in the determination of orientations. This improvement is accomplished by successive use of more finely-sampled reference projections. Two different workflows are suggested: with defocus groups or without (gold-standard refinement). For more information, see: [[http://spider.wadsworth.org/spider_doc/spider/docs/techs/recon/mr.html][SPIDER documentation on projection-matching]]

highres (3D refinement)
- This is a 3D refinement protocol whose main input is a volume and a set of particles. The set of particles has to be at full size (the finer sampling rate available), but the rest of inputs (reference volume and masks) can be at any downsampling factor. The protocol scales the input images and volumes to a reasonable size depending on the resolution of the previous iteration. The protocol works with any input volume, whichever its resolution, as long as it is a reasonable initial volume for the set of particles. The protocol does not resolve the heterogeneous problem (it assumes an homogeneous population), although it is somewhat tolerant through the use of particle weights in the reconstruction process. It is recommended to perform several global alignment iterations before entering into the local iterations. The switch from global to local should be performed when a substantial percentage of the particles do not move from one iteration to the next. The algorithm reports the cross correlation (global alignment) or cost (local) function per defocus group, so that we can see which was the percentile of each particle in its defocus group. You may want to perform iterations one by one, and remove from one iteration to the next, those particles that worse fit the model.

picking consensus (Particle picking)
- Protocol to estimate the agreement between different particle picking algorithms.

Then, a coordinate is considered to be a correct particle if M pickers have selected the same particle (within a radius in pixels specified in the form). If you want to be very strict, then set M=N; that is, a coordinate represents a particle if it has been selected by all particles (this is the default behaviour). Then you may relax this condition by setting M=N-1, N-2, ... If you want to be very flexible, set M=1, in this way it suffices that 1 picker has selected the coordinate to be considered as a particle. Note that in this way, the cleaning of the dataset has to be performed by other means (screen particles, 2D and 3D classification, ...).

tomo fill mw
- This protocol is a wrapper of *e2tomo_mwfill*. This program can be used to fill in the missing wedge of a SetOfTomograms with useful information based on a neural network
-
tomo initial model (Initial model)
- This protocol wraps *e2spt_sgd.py* EMAN2 program. It will take a set of subtomograms (particles) and a subtomogram(reference) and build a subtomogram suitable for use as initial models in tomography. It also builds a set of subtomograms that contains the original particles plus the score, coverage and align matrix per subtomogram .
-
tomo reconstruction (3D reconstruction)
- This protocol wraps *e2tomogram.py* EMAN2 program. Tomogram reconstruction from aligned tilt series. Tomograms are not normally reconstructed at full resolution, generally limited to 1k x 1k or 2k x 2k, but the tilt-series are aligned at full resolution. For high resolution subtomogram averaging, the raw tilt-series data is used, based on coordinates from particle picking in the downsampled tomograms. On a typical workstation reconstruction takes about 4-5 minutes per tomogram.

subset (Tools)
- Create a set with the elements of an original set that are also referenced in another set. Usually there is a bigger set with all the elements, and a smaller one obtained from classification, cleaning, etc. The desired result is a set with the elements from the original set that are also present somehow in the smaller set (in the smaller set they may be downsampled or processed in some other way). Both sets should be of the same kind (micrographs, particles, volumes) or related (micrographs and CTFs for example).

filter by normal
- This protocol takes surfaces or ROIs (SetOfMeshes) and a SetOfSubtomograms or SetOfCoordinates3D with transformation matrix and filters them by different criteria related with the normal direction.
-
picking consensus
- Protocol to estimate the agreement between different particle picking algorithms. The protocol takes several Sets of Coordinates calculated by different programs and/or different parameter settings. Let's say: we consider N independent pickings. Then, a coordinate is considered to be a correct particle if M pickers have selected the same particle (within a radius in pixels specified in the form). If you want to be very strict, then set M=N; that is, a coordinate represents a particle if it has been selected by all particles (this is the default behaviour). Then you may relax this condition by setting M=N-1, N-2, ... If you want to be very flexible, set M=1, in this way it suffices that 1 picker has selected the coordinate to be considered as a particle. Note that in this way, the cleaning of the dataset has to be performed by other means (screen particles, 2D and 3D classification, ...).
-
remove duplicates
- This protocol removes coordinates that are closer than a given threshold. The remaining coordinate is the average of the previous ones.
