You may have some luck by trying the following:

head -n2 YOUR-FILE.bvars (replacing YOUR-FILE.bvars of course with an actual bvars file. ;) )

For example:

niels@niels-mrlab:~$ head -n2 /home/niels/example_first/first-R_Puta_first.bvars
this is a bvars file
/usr/local/fsl/5.0/data/first/models_336_bin/05mm/R_Puta_05mm.bmv

Hopefully by using that second line, you can sort out which analysis was done on which computer.

Hi everybody!

I did a stupid mistake and I am here to know if I can make it right.

I wanted to perform FIRST-based shape analysis on a rather big sample (>1700 subjects).
Since I had so many subjects, to speed up things, I launched several batch on at least 3 different computers, using the run_first_all command.

Now I have all my subjects with the subcortical structure segmented, but when I try to concatenate the bvars for the sape analysis I get the "bvars were generated with different models" error message. A plausible message, since I have segmented subjects on three machines.

The problem is that because of the way in which the batch were written, I am no longer able to know which subject has been segmented on which machine.
Since I know that the great majority of subjects have been segmented on one computer and only a minority have been segmented on the other two, the best thing for me would be to get the information about who was segmented were, and then re run only those subjects which have been segmented on the "other two" computers.

Is there an information about the model used in the bvars ? Is there a way in which I can extract this information ?

I will be forever thankful for any suggestion!

Best

Alain
