I apologize!
I think I have just realized that I can create one base based on 4 time
points, right?

recon-all -base <templateid> -tp <tp1id> -tp <tp2id> -tp <tp3id> -tp
<tp4id> -all

Thank you!

>> Dear FreeSurfer Team,
>>
>>
>>
>> We are analyzing some longitudinal data (baseline [0], 6 months, 1 year,
>> 1.5 years) using FreeSurfer 7.4.1.
>> We already analyzed two timepoints (basline[0] and 6 months) but now we
>> are trying to look at 4 timepoints in total.
>>
>> I was wondering what the best way would be to do this. For the
>> longitudinal processing, should we create 3 bases/within-subject templates
>> between 0-6 months (this is already done), 0-1year, 0-1.5years), or between
>> 0-6months, 6months-1year, 1year-1.5years. Or both?
>>
>> Also, is it okay to correct/edit only the bases?
>>
>>
>> After the longitudinal processing, can we create a Longitudinal Table and
>> apply the two-stage model (LongitudinalTwoStageModel) method? Or because of
>> the 4 time points, we need to apply something else.
>>
>> Thank you for your help in advance!
>>
>>
>>
>> All the best, Eszter
