I have two questions regarding using the labels with tksurfer:

1. What exactly has been done to change the .label (e.g. lh BA44.label) to .thresh.label (e.g. lh BA44.thresh.label?

2. The instructions on this page 

to overlay the labels and set the Min and Max do not seem to work for me - I cannot seem to alter the Min from 2 and the Max from 5. Any thoughts as to why?

thanks very much!
