Can't find Destrieux Atlas .nii file online

I am looking for a .nii file for the Destrieux atlas so that I can add it as an atlas within MRIcron/MRIcroGL. I know how to add atlases, the issue instead is that I cannot find where to access the Destrieux Atlas .nii file, e.g. the equivalent of the default all.nii atlas. Does anyone know where I can download this?; Is there a website with all of the available atlases that I am missing?

Thanks in advance!

RE: Can't find Destrieux Atlas .nii file online
You can get the file online, but you will want to make a few corrections to make it useful:

1. Download the Destrieux Volume
2. Use MRIcroGL Import/Tools/Resize to convert from 32-bit float to 16-bit integer (regions of interest must be integers, e.g. no such thing as 'Area 16.211')
3. Use MRIcroGL Layer's Panel Options/ShowHeader option to change intention to Labels and save corrected header.

Here is a link to the Atlas after these steps have been followed:
