CMTK is a set of command-line tools for computational morphometry of biomedical images. CMTK contains tools for (1) registration (affine and nonrigid, single and multichannel, pairwise and groupwise); (2) image correction (MR bias field estimation, interleaved image artifact correction, EPI unwarping); (3) processing (filters, combination of segmentations, shape-based averaging); and (4) statistics (t-tests and the general linear model).
Allocate an interactive session and run the program.
Sample session (user input in bold):
[user@biowulf]$ sinteractive salloc.exe: Pending job allocation 46116226 salloc.exe: job 46116226 queued and waiting for resources salloc.exe: job 46116226 has been allocated resources salloc.exe: Granted job allocation 46116226 salloc.exe: Waiting for resource configuration salloc.exe: Nodes cn3144 are ready for job [user@cn3144 ~]$ module load cmtk [user@cn3144 ~]$ [user@cn3144 ~]$ exit salloc.exe: Relinquishing job allocation 46116226 [user@biowulf ~]$
Create a batch input file (e.g. cmtk_job.sh). For example:
#!/bin/bash set -e module load cmtk cmtk registrationx --dofs 12 --min-stepsize 1 -o 2_rigid.xform minimal.nii minimal2.nii
Submit this job using the Slurm sbatch command.
sbatch [--cpus-per-task=#] [--mem=#] cmtk_job.sh
Create a swarmfile (e.g. cmtk_jobs.swarm). For example:
cmtk registrationx --dofs 12 --min-stepsize 1 -o 2_rigid.xform minimal.nii minimal2.nii cmtk registrationx --dofs 12 --min-stepsize 1 -o 2_rigid.xform minimal.nii minimal2.nii cmtk registrationx --dofs 12 --min-stepsize 1 -o 2_rigid.xform minimal.nii minimal2.nii cmtk registrationx --dofs 12 --min-stepsize 1 -o 2_rigid.xform minimal.nii minimal2.nii
Submit this job using the swarm command.
swarm -f cmtk_jobs.swarm [-g #] [-t #] --module cmtkwhere
-g # | Number of Gigabytes of memory required for each process (1 line in the swarm command file) |
-t # | Number of threads/CPUs required for each process (1 line in the swarm command file). |
--module cmtk | Loads the cmtk module for each subjob in the swarm |
