Only fmc.odd.sm5.nii.gz is in the same dimensions as the f.nii.gz. However, I found a flag in the selxavg3 (-no-con-ok)that I do not need to specify a contrast. If I am not mistaken, all is good now. Thank you for your response.

That file should be in the same dimensions, no?

I just noticed that that file "fmc.odd.sm5.nii.gz" is created after selxavg3-sess. I was wondering how can I preprocess the functional image and have the output with the same dimension as the f.nii.gz without performing any contrasts. I just need to look at the signal in some ROIs without performing any contrasts. I hope this makes sense.

Thanks,
Ash

Hello,

I have several nifti files. I have preprocessed some of them before. I used this command: 
preproc-sess -s sess01 -fsd bold -stc odd -surface self lhrh -mni305 -fwhm 5 -per-session -force

The output files contained fmc.odd.sm5.self.lh.nii.gz, fmc.odd.sm5.self.rh.nii.gz, fmc.odd.sm5.mni305.2mm.nii.gz, and fmc.odd.sm5.nii.gz. Which this last one (fmc.odd.sm5.nii.gz) was the file that I needed for my further analyses. However, when I run the same command on another nifti file which was obtained from the same scanner and the same session, the output doesn't have the fmc.odd.sm5.nii.gz. 

I ran it several times but it never gave me that file. Also, it doesn't give me any errors.

I appreciate any help.

Ash
