I am loading the bfloats through tksurfer, not tkmedit, using the
File-Load Overlay dialogue window.
Sorry about that, I was confused for a minute.
I just built a version from that date and it can load a bfloat volume
correctly. Can you try loading the volume in tkmedit? If it can't load
there, there might be a problem with the volume itself.
Another source of potential error is a mismatch between the tksurfer
binary and its interface file (tksurfer.tcl); have you ever tried doing an
upgrade or replaced some files in your distribution that might have caused
this? You can check by getting the versions of both. Send me the output of
the following commands:
tksurfer --all-info
head $FREESURFER_HOME/lib/tcl/tksurfer.tcl

Maybe it's the case that that version of tkmedit can't load
bfloats that
way. Have you tried specifying directory and stem, i.e.:
/path/to/data/beta_doss-thickness-250-lh
for beta_doss-thickness-250-lh_000.bfloat?
I tried a number of other files and got the same error in all cases.
1) From the same glm analysis, on the same average7 surface:
beta_doss-thickness-250-lh_000.bfloat
beta_doss-thickness-250-rh_000.bfloat (in a different session
with the rh surface)
2) and from a different glm analysis:
y_doss-thickness-250-lh_000.bfloat (with a different average7
surface from that study)
Are there any others I should try to load?

Thanks for your prompt response.
Is this the most current version of FreeSurfer?
We have the 07-24-2003 version, however I am sure that we
saw
this working with this version of Freesurfer last summer. If
possible we would prefer to stick with our current version and
avoid updating and re-installation.
What input are you giving to load the bfloat?
In tksurfer File-Load Overlay, we specified the file y_doss-
thickness-250lh_000.bfloat

Hi Brian,
Thanks for the e-mail. Unfortunately we are still
having
problems getting the graph window to appear. Here is what
we
have:
1)
load the y values into tksurfer to see scatter plots.
We tried to load the .bfloat file as an overlay, and got
this
message in the log window:
sclv_read_bfloat_values: error in FunD_New
Not a directory
2) Here are the messages I get in the log window when
loading
y_doss-thickness-250lh.fsgd file (No graph window appears):
INFO: ignoring tag Creator
INFO: ignoring tag SmoothSteps
INFO: ignoring tag SUBECTS_DIR
INFO: ignoring tag SynthSeed
Read one slice only. Did you put all the slices in the
same
directory? WARNING: Could not get the graph title.
WARNING: Could not get the measurement label.
WARNING: Could not get the subject name.
WARNING: Could not get the data file name.
ERROR: Could not get number of classes.
Thanks for your help,
Robert
