I mentioned this in a previous email and was told that I should be using niml.write() and visualize using SUMA. I decided against this because not only would it fail to open with our version of SUMA (I can include the error if that would be helpful)

Indeed, that would be helpful.

Not at the moment, but it would be nice to support GIFTI. Currently surface anatomy can be exported as GIFTI, but there is no support currently for functional files. I’ve added an issue [1], so it may be added in the future.

ConvertDset (included with AFNI) can convert between NIML and GIFTI, and mris_convert (included with Freesufer) can convert between GIFTI and a variety of other file formats used in FreeSurfer.
