Dear Dual Regression Experts,
I have faced a bizarre problem in running my Dual Regression and appreciate if you can help me to solve it.
I get empty output from Dual Regression meaning that there is no stage 1 and 3 files.
I followed up all suggestions on the JISCMAIL about the similar issue but I still have the same problem.
This is the script I run for DR and I think there is no problem (as I used the same syntax and got results with other data)
dual_regression /Users/samansarraf/Desktop/ADRS2mm.gica/groupmelodic.ica/melodic_IC 1 /Users/samansarraf/Desktop/AD_Matrix_Design/AD_Matrix_Design.mat /Users/samansarraf/Desktop/AD_Matrix_Design/AD_Matrix_Design.con 10000 DRADNEW `cat /Users/samansarraf/Desktop/ADRS2mm.gica/.filelist`
I took a look at /Users/samansarraf/DRADNEW/scripts+logs/drD and it includes no error message and just includes (as an example):
/Users/samansarraf/Downloads/FSL/fsl/bin/fslmerge -t DRADNEW/dr_stage2_ic0000 `$FSLDIR/bin/imglob DRADNEW/dr_stage2_subject*_ic0000.*` ; /Users/samansarraf/Downloads/FSL/fsl/bin/imrm `$FSLDIR/bin/imglob DRADNEW/dr_stage2_subject*_ic0000.*` ; /Users/samansarraf/Downloads/FSL/fsl/bin/randomise -i DRADNEW/dr_stage2_ic0000 -o DRADNEW/dr_stage3_ic0000 -m DRADNEW/mask -d /Users/samansarraf/Desktop/AD_Matrix_Design/AD_Matrix_Design.mat -t /Users/samansarraf/Desktop/AD_Matrix_Design/AD_Matrix_Design.con -n 10000 -T -V
...
Where ic0000 ends to ic0064.
Then, I opened drD.exxxx.y files , and most of them have this error message:
Image Exception : #22 :: ERROR: Could not open image DRADNEW/dr_stage2_ic000X(varies from 0 to 49 - # of components from MELODIC)
ERROR: Program failed
An exception has been thrown
ERROR: Could not open image DRADNEW/dr_stage2_ic000X Trace: read_volume4DROI.
Also, in the rest of files, I have this error:
Usage: /Users/samansarraf/Downloads/FSL/fsl/bin/imrm <list of image names to remove>
NB: filenames can be basenames or not
randomise options: -i DRADNEW/dr_stage2_ic00X -o DRADNEW/dr_stage3_ic00X -m DRADNEW/mask -d /Users/samansarraf/Desktop/AD_Matrix_Design/AD_Matrix_Design.mat -t /Users/samansarraf/Desktop/AD_Matrix_Design/AD_Matrix_Design.con -n 10000 -T -V

As I have a deadline in couple of days, I do appreciate if somebody can help in this matter.
