For FreeSurfer (FS) stats files, aseg.stats and ?h.aparc.stats, pyxnat (branch bbrc) includes a set of handy functions to collect the content of such text files and structure it as tables (Pandas dataframe).
Bugs found in the current
pyxnat.core.derivatives.freesurfer.aparc()function logic,Hemisphere-specific measures 'NumVert', 'WhiteSurfArea', and 'MeanThickness' had side column not registered when parsed as table. Making it impossible to identify the hemisphere they relate to.
Global brain-wide measures (volume-related copied by FS from aseg.stats into aparc.stats) 'BrainSegVol', 'BrainSegVolNotVent', 'BrainSegVolNotVentSurf', 'CortexVol', 'SupraTentorialVol', 'SupraTentorialVolNotVent' and 'eTIV' were registered twice in the aparc table, one per hemisphere. Thus, having duplicated rows with the same data content.
This PR revises the
aparc()function code to fix the mentioned bugs.
