Dear Torsten,

Thank you for your reponse on this! Chris Rorden said that there might be some slight errors in the text file. If following template conventions, the first column is the index, followed by a name, followed by red, green, blue and alpha values.

However, some rows only have the red values, e.g.,:
"234 l_ 1 188 folium-tuber 255"
Unlike other rows, eg "242 l_simple_lobule 27 151 223 255"
Similar errors appear for 282, 299, 320, 377, 380, 385, 400, 407, 422, 423, 440, 442,443, 468, etc.

Were those values meant to be read as zeros?

Using Slicer however, I can make the labels appear, so there must be differences in the way Slicer and MRICron are reading the text files.It may also still be the differences in filetype- MRICron is made for reading 256 labels while the template was made with many more labels.

Best,
Li-Ann
