<p>Hi Emma,</p>
<p>The problem is that wb_view only supports float32 while python
likes to convert everything to float64. The produced gifti file
opens normally in wb_view, when I convert your data to float32
just before creating the data arrays (see attached file).</p>

<div>I have a problem reading giftis that I write from nibabel.
It works if I replace the data with data taken straight out of
another gifti data array, but if I add a matrix of floats I am
unable to read it into the HCP's workbench viewer, not use the
FSL gifti reader. I get the following error messages:</div>
<div><br>

<div>I've attached some test code and the gifti file I tested it
with. Any suggestions of how to fix this would be appreciated,
