Hello everyone,

I created ROIs using the Mango program and added 8 ROIs in the setup for all subjects, I wish to add two more but I am getting the following error when I am uploading them. Is there a limit to how many ROIs can be added or is there something wrong with the ROIs themselves? I have attached one of the ROI nii files here too.

ERROR DESCRIPTION:

Error using read_hdr (line 52)
Unrecognised datatype (12053.000000) for "C:\Users\jclab\Desktop\spelling_study_2017\STG_roi.nii".

Error in conn_getinfo (line 18)
V=spm_vol(filename);
Error in conn_file (line 3)

Error in conn_filesearchtool (line 86)
if length(h.callback)>1, feval(h.callback{1},h.callback{2:end},names); else, feval(h.callback{1},names); end

Thanks for your help!

Hi Kulpreet,

The attached STG_roi.nii file does not look like a valid nifti file (it does not seem to have the expected size nor any of the default headers fields expected in a validly-formatted nifti volume). Could you please elaborate on how this file was constructed?

Best
Alfonso
