AFNI

Description

afni website  

AFNI is a set of C programs for processing, analyzing, and displaying functional MRI (FMRI) data - a technique for mapping human brain activity. It should be used for research purposes only.

Required Modules

Serial

• afni

System Variables

• HPC_{{#uppercase:afni}}_DIR

Additional Information

Starting with version 2016_2_09 - the first AFNI version on HiPerGator2 - use the 'launch_afni' command to access afni executables. In addition, if you use absolute paths (starting with /ufrc/) in your arguments you have to convert them to relative paths. We have a relative_path script in the ufrc module for it. For example, the following commands in a job script will run the 3dcalc analysis:

module load ufrc afni
launch_afni 3dcalc -a $(relative_path /ufrc/group/user/Map_repository/S01_19_DA/fnirted_FA.nii.gz) -expr 'step(a)' -prefix $(relative_path /ufrc/group/user/test_afni.nii.gz)

If you already use relative paths then the use of 'relative_path' is not required.
