Unexpected behavior for parcellation label picking

[Aaronearlerichardson]

Intended Behavior

The popTaskSubjectData script determines the volume label for each electrode according to the following rules:

In volume percentage order, what brain parcellations are contained within a 3 mm radius of an electrode?

1. If the parcellation contains the keyword White-Matter and is a volume percentage of <80%, consider the next largest volume label
2. If the majority parcellation label contains the keywords Unknown or hypointensities and is <100%, consider the next largest volume label.

Actual Behavior

relevent snippet:

Lines 210 to 232 in 08132fb

	for iElec=1:size(TXT,1)
	elec_nameT=strcat(Subject(SN).Name, '-',Tname(iElec,:));
	iN=1;
	while (contains(Trest(iElec,iN),'White-Matter')) && iN<=7 && NUM(iElec,iN)<0.8
	%|| NUM(iElec,iN-2)<0.5
	iN=iN+1;
	end
	% while (contains(Trest(iElec,iN),'Unknown') || contains(Trest(iElec,iN),'unknown') || contains(Trest(iElec,iN),'hypointensities') ) && NUM(iElec,iN)==1
	% subj_labels_loc(iElecS+iElec)='Unknown';
	% end
	while (contains(Trest(iElec,iN),'Unknown') || contains(Trest(iElec,iN),'unknown') || contains(Trest(iElec,iN),'hypointensities') ) && NUM(iElec,iN)<1 && iN<=7
	%|| NUM(iElec,iN-2)<0.5
	iN=iN+1;
	end
	subj_labels2(iElecS+iElec)=elec_nameT;
	%
	subj_labels_loc(iElecS+iElec)=Trest(iElec,iN); % percentages
	% subj_labels_loc{iElecS+iElec}=TXT(iElec+1,1); % first column
	end

This code runs these rules, but in sequential order. This means that if a label breaks rule 2, and then the next label breaks rule 1 it will not be caught. An example of this test case might be:

[Unkown, 0.40], [Left-Cerebral-White-Matter, 0.31], [ctx_lh_G_temporal_middle, 0.29]

Will incorrectly choose the label Left-Cerebral-White-Matter when it should choose ctx_lh_G_temporal_middle
