Hey :),
I'm using the Extract ROI time series button in DPARSF 4.0 and with the Template of Craddock's 400 ROIS from the DPABI folder. Strangely only 392 ROIs get extracted although the template has 400 ROIs in it.
Any ideas what the problem could be?

Hey,
Hey,
Maybe I could not answer your question, and this is my question: Extract ROI means Extract some brain regions you are interested in and then for the analysis later. right? and except for the standard template, how could I define own template?
Hope to hear from you soon. Thank you.
Using which template is based
Using which template is based on your hypothesis.
There must be only 392 ROIs
There must be only 392 ROIs in that template file, you can check that.
I read in the nifti in matlab
I read in the nifti in matlab and checked how many label numbers there are. There are numbers from 1 to 400, so that's why I'm confused that only 392 rois were extracted :(
You can use:
You can use:
length(unique(Data(:)))
to check how many distinct labels are there.
I guess there must be some numbers skipped.

In the template are
In the template are definitely 400 ROIs, but DPARSF only recognizes 392. Not sure why that is, maybe you can check if you get the same problem.

Ah yes, it seems there are
Ah yes, it seems there are some numbers missing..so basically there are only 393 ROIs but the highest number is 400. That there are fewer clusters than "requested" is mentioned on the website, didn't see it before: http://ccraddock.github.io/cluster_roi/atlases.html
