Hi Anna,

that was not my suggestion, I suggested to pass both the cross sectional time point ID and the base id (together with the long flag) and additionally the -localGI flag.

So if you time point 1 is XXX_1 and time point 2 is XXX_2 and your base is XXX_base then

recon-all -long XXX_1 XXX_base -localGI

and for the second time point

recon-all -long XXX_2 XXX_base -localGI

The base is not one of your time points, it gets created in the -base step and you give it a name (here XXX_base). In order for the above to work you need 5 directories per subject:

the 2 cross
XXX_1 and XXX_2
the base
XXX_base
the results of the -long runs:
XXX_1.long.XXX_base
XXX_2.long.XXX_base

the last two are the ones where the GI will be created.

Best, Martin

hi Martin, I just tried this and it resulted in errors/ Do I not have to specify a flag for the baseid or for each subject, eg -s?

What I did (according to your suggestion)

recon-all -long XXX_1.long XXX_2.long -localGI

This did not work? Do you know why potentially?

Hi Anna,

no, you would still do:

recon-all -long tpid baseid -localGI

just not use the '-all'.

Best, Martin

thank you. But if the lnog process has already been done and these induviduals already have long directories so to speak, I would just put the lgi flag on as normal but just replace the subject name with the long subject name eg ?
recon-all -s XXXX_long -localGI

Thank you

Hi Anna,

for the image processing, you just add the lgi flag to the regular longitudinal recon-all command
recon-all -long ……     -lgi

for the analysis after that you use the long directories.

Best, Martin

Dear group,

If I want conduct gyrification analyses on the long runs that have been through the longitudinal stream, do I just perform the "normal" baseline command on the .long data?

thank you,

kind wishes

Anna
