Hi Linn

I think it means after you convert the stats file into a format that whatever stats package you are going to use can read.

Dear freesurfer experts,

I have a question. I am trying to complete the longitudinal tutorial, and in freeview tutorial it states:

"In order to analyze your longitudinal data, you have different options. You could, e.g., open the stats text files in each tpN.long.templateID/stats/ dir, containing statistics such as volume of subcortical structures or thickness averages for cortical regions. These statistics can be fed (after conversion) into statistical packages to run whatever analysis you are interested in"

I am wondering what exactly "after conversion" refers to ( I encountered the same phase in the other recon option (ie cross-sectional). I was under the impression that the values from the stats files are the ones to use; thus what does after conversion refer too?

Kind Regards, Linn
