Hi Seulgi

you can specify the fthresh and and slope on the command line using:

tksurfer ... -fthresh <threshold> -fslope <slope>

or alternatively, both the min and max using

tksurfer ... -fminmax <threshold> <max>

where <max> is the value at which the color saturates. Or you can set the thresholds based on rank ordering of the values using percentiles instead of absolute values:

-pthresh <min> <mid> <max>

I'm using 'freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0' and I have a problem.

I used a command 'tksurfer fsaverage lh inflated -ov surfdata' on teminal.

Then, I used 'configure overlay display' in veiw>configure>overlay to set proper threshold.

I could set approximate threshold values easily by mouse.

But I wanted to set the values by keyboard inputs(exact numbers).

I think there is a way to type numbers(in my case, it is unable to type any words on the edit boxes).

How can I do?
