Hi Anson,

'conversion' means to extract the values from that file (for the specific structure(s)) and put them into a format that can be read by your program (SPSS). For the stats you would not use qdec anyway (you could use mri_glmfit).

You may want to check out asegstats2table and aparcstats2table to grab the values from the stats files and put them into a table format.

Best, Martin

Hi,

In the longitudinal tutorial it states that: “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, such as linear mixed effects models (often used in longitudinal analysis).

I am wondering what conversion this refers to? I would like to run the stats in SPSS without having to use qdec for now.

Any help would be great

Best
