Hi (probably pt) :)

Per your suggestion, I changed the number of iterations from 50 to 300 for 3dDWUncert. I guess it makes sense that this would now extend the processing time of this command. However, I'm wondering what a *reasonable* amount of time would be. For instance, I am running our subjects (n=330) in parallel across 32 cores. After 3 days, I have gone in to check and it's only at ~20-30% for the first batch of 32 subjects. At this rate, I've calculated everything to be completed in 3 months! This seems abnormally long. Does my command below seem ok?

find SPN01* -type f | nohup parallel 'cd {} && cd afni && 3dDWUncert -inset ../data.nii.gz -prefix DWUncert -input 3dDWItoDT_ -bmatrix_FULL dwi_matA.txt -iters 300 -overwrite' ::: * > nohup_3dDWUncert.out &
