Your original labels are not on fsaverage. You need to transfer them to fsaverage using mri_label2label. That should fix your first problem. The 2nd should be fixed by having your ctab go from 0 to 58 with 0 being the unknown label doug

Hello,
I have a set of custom labels and I want to plot them all at once on one brain, so I'm trying to use mris_label2annot for that. However, I'm getting several problems. Here is an example of what I get:

The labels I'm using were originally defined on a decimated source space (that was created using the MNE toolbox), so it's normal that most of them show up as lots of dots rather than contiguous areas. However, I don't know why some of them actually are showing up as contiguous areas; when I plot the labels one by one, all of them show up as series of dots rather than contiguous areas, so it seems that creating the annotation is messing something up.
I also have a few other problems that you can't see in the image. Firstly (and most seriously), the locations of the labels that show up when I plot this annotation do not at all match where the labels actually are--that is, if I hover my mouse over one of the labels in this, it doesn't match where the label actually should be if I plot that label by itself.
Secondly, there seems to be some indexing issue with my color lookup table--I have 58 labels per hemisphere, so I created a color table that starts at label 0 and goes up to 57 (as per the example at http://ftp.nmr.mgh.harvard.edu/fswiki/LabelsClutsAnnotationFiles and the automatically-generated annotations such as lh.aparc2009s.annot). In my color lookup table, label 0 is called 'amygdala' and label 1 is called 'anteriorcommisure'. But when I actually run mris_label2annot, the output seems to suggest that the program is 1-indexed instead of 0-indexed (because it skips the 0th label, andlooks for the 57th label, see output snippet below):

Does anyone have suggestions about any or all of these issues?
