Dear David and Matt,
Thanks a lot! The problem is solved. Indeed, the flat coord-file was assigned to the wrong cut topology file.
Kind regards,
Marc Van Baelen

I think you are loading the wrong cut topology file when you open the spec
file.  Try some of the other topo files in the spec file till you find the
one that looks right.

Peace,

Matt.

Subject: [caret-users] FW: Flat map distortions

Dear all,

To clarify the flat map distortion problem that I have posted in a previous
message, I added some image capture files.

I have the following problem making flat maps using CARET 5.51. When the
flat map is finished, it looks fine. When I close CARET and reopen it again,
the flat map looks striped. I made an 'image capture' of the flat map before
I closed CARET (see image 'flatmap_normal') and when I reopended the flat
map (see image 'flatmap_striped'). I have the impression that the stripes
converge to a central point on the flat map. Does anyone have an idea how to
get rid of these stripes? I use the flat map to select a region of interest
and I am afraid that the stripes might influence the selection. When saving
the aligned surface files, I use the default options (indicated in the
manual).

Kind regards,
Marc Van Baelen

Marc,

Matt's analysis is correct.  But if you have multiple topo files
loaded, use the Surfaces: Topology: Set Topology Assigned to Surfaces,
select the flat coord file, and assign it to the the desired cut
topo.  Once duly assigned, then save the flat coord file (overwriting
the old version) to preserve this default assignment.
