Hi Corina, At this time, Connectome Workbench is not able to display RGBA files. I do not know when, or if, display of RGBA files will be added.
As Matt Glasser indicated in his response, you may want to try using a Label file. A label file contains integers where each value is an index into a table of names.

I created this RGBA file with nibabel using values between [0,1]. gii_arr = gifti.GiftiDataArray(data=color_data,intent="NIFTI_INTENT_RGB_VECTOR") gii_img = gifti.GiftiImage() gii_img.add_gifti_data_array(gii_arr) gifti.giftiio.write(gii_img, 'test.rgba.gii') When loading this file into wb_view, all faces are coloured blue instead of the defined color codes. How is this file supposed to be formatted to show the defined coloring? Am I getting the idea of this kind of file wrong? I also tested with an rgb file which has been provided for caret some time ago (https://www.nitrc.org/forum/forum.php?offset=125&max_rows=25&style=flat&forum_id=281&thread_id=). The overlay is also just blue and not as shown in their provided screenshot. [workbench version 1.2.3] Thanks for your help, Corina _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
