tkmedit error message

[Rutvik Desai]

I am a new user of freesurfer. I was able to complete
the first three steps of the process, namely, convert/average,
process volume, and create surface. However, I do not get any
graphic displays showing surfaces or slices. When I go to the next step,
Edit Segmentation, no displays open up and this error is shown:

/home/rdesai/fs/bin/Linux/tkmedit: error while loading shared
libraries: libppm.so.1: cannot load shared object file: No such file or
directory.

Seems like it is looking for an old version (1) of the ppm
libraries. On our machines currently we have version 9. Is there a way
around this problem?

thanks,
Rutvik

viewing functional overlay

[Rutvik Desai]

In attempting to use the surface-stats button to
see functional overlay, in the View Functional Data
option, this error is generated and tksurfer does not start:

'Error: can't read scandirpref: no such variable.'

The stack trace is at the end of this message if that helps in locating
where the error was generated.

Also, an error is generated when using volume-stats regarding not
recognizing the -invphaseflag option. tkmedit ignores this option
and is able to display the functional data. It appears that the
current version of tkmedit does not recognize three options,
-invphaseflag,  -scalebarflag,  -colscalebarflag, that are used
by csurf to call tkmedit when using volume-stats. This is not
a big problem but it does display an error before starting tkmedit.

thanks,
Rutvik
