Dear all,

 

I am very new to freesurfer so I might be asking an obvious question and I am sorry about that. I tried to find this in the archives but did not find a solution.

 

I am have done the following steps successfully for images at t0 and t1 while doing the longitudinal processing but I am stuck at the 3^rd step: 

 

First step:

recon-all -subject 01_t0 -i /subjectfiles/t0/sanlm_13.nii -all -qcache -notal-check

 

recon-all -subject 01_t1 -i /subjectfiles/t1/sanlm_13.nii -all -qcache -notal-check

 

Second step:

 

recon-all -base 01_t0t1template -tp 01_t0 -tp 01_t1 -all

 

 

Third step (Where I have an error):

 

recon-all -long 01_t0 01_t1 01_t0t1template -all

 

ERROR: Flag 01_t0t1template unrecognized.

-long 01_t0 01_t1 01_t0t1template -all

Thanks in advance,
