<div dir="ltr">Dear FieldTrip community,<div><br></div><div>I try to follow this instruction
(<a href="https://www.fieldtriptoolbox.org/tutorial/salzburg/#perform-sourcanalysis">https://www.fieldtriptoolbox.org/tutorial/salzburg/#perform-sourcanalysis</a>)
to create a ROI mask as follows: <br></div><div><br></div><div>atlas = ft_read_atlas(fullfile(ftpath, 'template/atlas/aal/ROI_MNI_V4.nii'));</div><div>sourcemodel = load(fullfile(ftpath, 'template/sourcemodel/standard_sourcemodel3d10mm'));<br></div><div><br></div><div>cfg = [];<br>cfg.atlas = atlas;<br>cfg.roi = atlas.tissuelabel(43);<br>mask = ft_volumelookup(cfg, sourcemodel);<br></div><div><br></div><div>However, after executing these lines, an instruction popped out and asked "Do you want to change the anatomical labels for the axes [Y, n]?". After specifying the MNI system, there was still an error message "Error using ft_volumelookup (line 248) the mismatch between the coordinate system in the atlas and the coordinate system in the data cannot be resolved"</div><div><br></div><div>Any help will be much appreciated!</div><div>Shen-Mou Hsu</div><div><br></div><div><br></div></div>
