Hi,

When running TRACULA with longitudinal data, is it necessary for all scan waves of a given subject to be included in a single dmrirc file? My initial thought was “no”, that it would be fine to run one scan wave per subject per dmrirc file (as long as the “baselist” variable is set appropriately for each scan wave and subject).

But looking at the ‘trac-all’ script, I see

if ($#baselist == 0) then #--->>> A single time point for each subject

…

else #--->>> Multiple time points for each subject

…

So, I’m wondering why different sections in the code would be necessary if in fact it is ok to process a single scan wave per dmrirc file.

thanks,

-MH
