Hi, I used the command

preproc-sess -s LD-functional -fwhm 5

However, the command does not seem create the fmcsm5.nii file. The process completes motion correction successfully, but it does not complete the spatial smoothing and brain masking. I get a "Motion correction SUCCESSFULLY completed" message but I only get a "Spatial smoothing done" message. I have already asked this question in the mailing list. and i was asked to check the writing permissions of the directories. I have changed the "bold" directory and freesurfer directory to have read, write and execute permisions using the "chmod -R 777" command.

I get the following output:
