Error using nearpoints: First arg must be a real 3xM array. #355

Hi,

Hope all is well!

I am trying to use AFQ on the tractography generated by Mrtrix. I am stuck in an issue that I do not understand well:

Error using nearpoints First arg must be a real 3xM array.

Error in dtiIntersectFibersWithRoi (line 156) [~, bestSqDist{ii}] = nearpoints(fc', roiCoords{ii}');

Error in dtiSplitInterhemisphericFibers (line 67) [fgToChop,contentiousFibers, keep] = dtiIntersectFibersWithRoi([], {'and'}, [], roi, fg);

Error in AFQ_SegmentFiberGroups (line 206) fg = dtiSplitInterhemisphericFibers(fg, dt, -10);

The size(fc') is 3x854991991, and size(roiCoords{ii}') is 3x2590. So, I am clueless on why they are not a 3*M array. Please pardon me if this question is very basic.

Any thoughts/advice would be much appreciated! Thank you!!

Best, Yanbin

It seems that the nearpoints need inputs to be double, and the problem should be solved here (convert the single to double for inputs).
