External Email - Use Caution

Dear Bruce, Thank u very much for replying. sorry I'm still a little bit doubtful, just as a confirmation:  by repeatable you mean I can repeat it and every time get a a new result? or every time the result will be the same? Best, Maedeh,   Hi Maedeh

I think it divides along the maximum variance eigen-axis, so should be  repeatable.

????????External Email - Use Caution????????   Dear experts, I use the file "lh/rh.aparc.annot" and a splitfile as the inputs of?the command "mris_divide_parcellation" in order to have a parcellation with more regions. Now I have a question: for example if in my splitfile I write 4 in front of the region

"precuneus",

...

how does it divide this region?into 4 subregions? Is it based on a specific pattern or it is

random?

...

I mean if I?repeat this command line 100 times with the same splitfile, will?the results be the same??I would be grateful if you could help me. Best regards, Maedeh,
