Dear Freesurfer experts,

I was trying to run some longitudinal analysis but whenever I want to use the commands “long_mris_slopes” or “long_qdec_table” I just get 
“command not found” as an answer. When I try to look up a package that might include the command, by typing “cnf long_mris_slopes”, 
I also just get “command not found” as an answer. We are currently using version v 1.313.2.6.

Does anyone of you know if the two commands that I would like to run, are included in this version? Where would I have to look for the 
additional package if it exists? Or am I by any chance just typing the commands incorrect?

Many thanks for the help!

Sincerely yours

Peter
