error during use of bsc_segmentSubCortical_v2.m #6

When attempting to run your segmentation, I'm running into an issue with line 122 of this function (see below). The error message I receive is: 'Error using == \n Matrix dimensions must agree'

I would expect this to occur when the category prior function fails to find any within hemisphere frontal to subcortical connections. Or at least whatever the name specified here is ('frontal_to_subcortical'). This is surprising because there's usually a great many tracts that meet this criteria (i.e. thalamaco-cortical connections). Might mean something is wrong with your data. Regardless, the oveararching problem is that this was not a safe call in the event that no streamlines are found. Remedied by using https://github.com/DanNBullock/wma_tools/blob/master/bsc_extractStreamIndByName.m

Will update and include in next recompile.

I believe this was fixed on July 20 with the addition of calls to https://github.com/DanNBullock/wma_tools/blob/master/bsc_extractStreamIndByName.m
