Overview

AITom

Introduction

AITom is an open-source platform for AI driven cellular electron cryo-tomography analysis.

AITom is originated from the tomominer library, adapted from an extended version of the tomominer library, developed at Alber Lab.

About us

Xulab at Carnegie Mellon University Computational Biology Department

Code and data for projects developed and maintained by Xu Lab and collaborators.

The research related to the code and data can be found at http://cs.cmu.edu/~mxu1

Background

Nearly every major process in a cell is orchestrated by the interplay of macromolecular assemblies, which often coordinate their actions as functional modules in biochemical pathways. To proceed efficiently, this interplay between different macromolecular machines often requires a distinctly nonrandom spatial organization in the cell. With the recent revolutions in cellular Cryo-Electron Tomography (Cryo-ET) imaging technologies, it is now possible to generate 3D reconstructions of cells in hydrated, close to native states at submolecular resolution.

Research

We are developing computational analysis techniques for processing large amounts of Cryo-ET data to reconstruct, detect, classify, recover, and spatially model different cellular components. We utilize state-of-the-art machine learning (including deep learning) approaches to design Cryo-ET specific data analysis and modeling algorithms. Our research automates the cellular structure discovery and will lead to new insights into the basic molecular biology and medical applications.

De novo structural mining pipeline results: (a). A slice of a rat neuron tomogram, (b). Recovered patterns (from left to right): mitochondrial membrane, Ribosome-like pattern, ellipsoid of strong signals, TRiC-like pattern, borders of ice crystal, (c). Pattern mining results embedded, (d). Individual patterns embedded.

make FAML running

entry function aitom.average.ml.faml.faml.test_EM_real_data

The method is based on the following paper:

Zhao Y, Zeng X, Guo Q, Xu M. An integration of fast alignment and maximum-likelihood methods for electron subtomogram averaging and classification. ISMB 2018. Bioinformatics. 2018 Jul 1; 34(13): i227–i236. doi:10.1093/bioinformatics/bty267. arXiv:1804.01203

Let's first fix the bugs to make the program run.

Facing problem running ProtoNet

Greetings,

I am currently facing a problem whenever I try to work with ProtoNet. As per the documentation, if I run python run_train.py, I get the following error.

Traceback (most recent call last):
  File "run_train.py", line 4, in <module>
    from train import main
  File "/shared/home/v_ajmain_yasar_ahmed_sahil/aitom/aitom/classify/deep/supervised/cnn/few_shot/protonet/train.py", line 20, in <module>
    from protonets.utils import data as data_utils
  File "/shared/home/v_ajmain_yasar_ahmed_sahil/aitom/aitom/classify/deep/supervised/cnn/few_shot/protonet/protonets/utils/data.py", line 1, in <module>
    import protonets.data
ModuleNotFoundError: No module named 'protonets.data'

Apparently, there is no protonets.data file under the directory protonets/utils where the file data.py resides. Am I missing something here?

Thank you.

tool for cropping tomogram
We can use numpy to crop a volume, but if we save the volume into a mrc file, the header information is incorrect. To solve this problem there are two possible ways:

try to find a command line tool to do such cropping. This command line tool may exist in bsoft package

write our own code to correct the header and write into the mrc file using the mrcfile package.

Following is how to crop a tomogram using bshow: To cut a subvolume using bshow: 1) choose micrograph / pick particles 2) set box size 3) in boxes menu, choose extract particles 4) may check individual output files. 5) use micrograph / write parameter file. You can first cut according to the low passed filtered map, save the cutted subvolume and star file, then modified star file and load it with the unfiltered tomogram. Then cut the unfiltered tomogram and save the subvolume.

Fixed regression introduced in v0.38.1 which broke parsing of wheel file names with multiple platform tags

0.38.1 (2022-11-04)

Removed install dependency on setuptools

The future-proof fix in 0.36.0 for converting PyPy's SOABI into a abi tag was faulty. Fixed so that future changes in the SOABI will not change the tag.

Dropped support for Python < 3.7

Updated vendored packaging to 21.3

Replaced all uses of distutils with setuptools

The handling of license_files (including glob patterns and default values) is now delegated to setuptools>=57.0.0 (#466). The package dependencies were updated to reflect this change.

Fixed potential DoS attack via the WHEEL_INFO_RE regular expression

Fixed ValueError: ZIP does not support timestamps before 1980 when using SOURCE_DATE_EPOCH=0 or when on-disk timestamps are earlier than 1980-01-01. Such timestamps are now changed to the minimum value before packaging.

0.37.1 (2021-12-22)

Fixed wheel pack duplicating the WHEEL contents when the build number has changed (#415)

Fixed parsing of file names containing commas in RECORD (PR by Hood Chatham)

Some modules are missing

Hi, I am looking through the repository especially for the simulation of tomogram data. However, as mentioned in the issue #167, there are some missing modules not publicly available such as aitom_core. Is there any plan to share those modules in the near future, hopefully?

Best Regards!

Gum-Net Training not improving with demo data

Hi,

I was testing the Gum-Net and for that used the provided demo data set. After around 30 epochs and around 15 hours of training I stopped it because there is no improvement in the loss function, please see below the logs of the training procedure.

Before finetuning: Rotation error: 1.7350925500744534 +/- 0.6650064011311111 Translation error: 8.442523177067761 +/- 3.44293514383784 ---------- Training Iteration 0 4/4 [==============================] - 1784s 404s/step - loss: 0.8216 Training Iteration 1 4/4 [==============================] - 1781s 405s/step - loss: 0.8218 Training Iteration 2 4/4 [==============================] - 1774s 404s/step - loss: 0.8251 Training Iteration 3 4/4 [==============================] - 1788s 406s/step - loss: 0.8274 Training Iteration 4 4/4 [==============================] - 1783s 405s/step - loss: 0.8334 Training Iteration 5 4/4 [==============================] - 1782s 405s/step - loss: 0.8201 Training Iteration 6 4/4 [==============================] - 1777s 405s/step - loss: 0.8250 Training Iteration 7 4/4 [==============================] - 1797s 407s/step - loss: 0.8310 Training Iteration 8 4/4 [==============================] - 1787s 407s/step - loss: 0.8336 Training Iteration 9 4/4 [==============================] - 1784s 406s/step - loss: 0.8207 Training Iteration 10 4/4 [==============================] - 1787s 406s/step - loss: 0.8258 Training Iteration 11 4/4 [==============================] - 1779s 405s/step - loss: 0.8235 Training Iteration 12 4/4 [==============================] - 1784s 406s/step - loss: 0.8296 Training Iteration 13 4/4 [==============================] - 1773s 402s/step - loss: 0.8271 Training Iteration 14 4/4 [==============================] - 1773s 403s/step - loss: 0.8199 Training Iteration 15 4/4 [==============================] - 1785s 406s/step - loss: 0.8315 Training Iteration 16 4/4 [==============================] - 1789s 407s/step - loss: 0.8264 Training Iteration 17 4/4 [==============================] - 1777s 405s/step - loss: 0.8336 Training Iteration 18 4/4 [==============================] - 1774s 403s/step - loss: 0.8299 Training Iteration 19 4/4 [==============================] - 1790s 407s/step - loss: 0.8303 Training Iteration 20 4/4 [==============================] - 1784s 406s/step - loss: 0.8244 Training Iteration 21 4/4 [==============================] - 1786s 407s/step - loss: 0.8242 Training Iteration 22 4/4 [==============================] - 1789s 406s/step - loss: 0.8245 Training Iteration 23 4/4 [==============================] - 1782s 406s/step - loss: 0.8253 Training Iteration 24 4/4 [==============================] - 1789s 405s/step - loss: 0.8258 Training Iteration 25 4/4 [==============================] - 1784s 406s/step - loss: 0.8238 Training Iteration 26 4/4 [==============================] - 1782s 405s/step - loss: 0.8200 Training Iteration 27 4/4 [==============================] - 1779s 405s/step - loss: 0.8282 Training Iteration 28 4/4 [==============================] - 1780s 405s/step - loss: 0.8251 Training Iteration 29 2/4 [==============>...............] - ETA: 19:00 - loss: 0.8142

Do you have any suggestions or explanation why the training with your demo dataset is not working? I did not change the source code.

Kind regards!
