I ran the command recon-all -all -s t2 -i t1xxxxx.mnc as Bruce suggested and the process took off but has been running for more than 6 hours and seems to be not doing anything after the step which reads MRISunfold() max_passes = 1 -----------

it has a few steps after that, but doesn't say that it completed. The last line reads -

randomSeed 1234. Is it hung? Should I exit the program?

Thank you for your help!
