Custom Templates Using Functional Connectivity Maps

Does anyone have an MRIcron compatible Yeo2011_7Networks ( template? I have a lesion map that I would like to overlay on the yeo template to quantify the number of lesioned voxels that overlap with the different networks (via MRIcron -> Draw -> Descriptive).

I have been unsuccessful at converting the freesurfer version (from the first link above) to work as a template in MRICron, despite following, despite changing header information as show at the bottom of this webpage:

I can also try this in MRIcroGL if anyone knows how to do the equivalent of MRIcron -> Draw -> Descriptive.

Many thanks in advance!
