Hello,
I am running into a major issue when I run recon-all -all on the OASIS1 cohort.
I am getting an inconsistent number of ROIs for the same subject between the lh
and rh, resulting in different sizes of connectivity matrices across subjects
(various numbers of ROIs {27, 28, 29, 30, 31,32}. For all subjects from other
cohorts, patients and controls, it was 31 ROIs).
I tried inspecting which ROIs usually cause this difference between the two
hemispheres, it differs from subject to subject, but here is a comprehensive
list of all the problematic ROIs that came up. Please not this is a cohort of
healthy controls this issue is coming up for. I ran this on a set of patients
with Multiple Sclerosis, and I got a consistent number of 31 ROIs.
{'insula', 'parahippocampal', 'caudalmiddlefrontal', 'parsorbitalis',
'paracentral', 'transversetemporal', 'parsopercularis', 'superiortemporal',
'postcentral', 'isthmuscingulate', 'inferiortemporal', 'superiorparietal',
'parstriangularis', 'middletemporal', 'rostralanteriorcingulate',
'lateraloccipital', 'entorhinal', 'posteriorcingulate', 'lingual',
'pericalcarine', 'inferiorparietal', 'precentral', 'cuneus', 'fusiform',
'lateralorbitofrontal',
'caudalanteriorcingulate', 'superiorfrontal', 'medialorbitofrontal',
'precuneus', 'supramarginal', 'temporalpole', 'rostralmiddlefrontal'}
Any idea what this might be due to? This is quite a big issue for our pipeline
so any help would be appreciated. Thanks, and looking forward to your response.
