This problem is probably caused by there being a copy of a FrameN.M (e.g. Frame1.0) file in your MCPATH that shouldn't be there. Here is how to determine if this is the case: o from the McIDAS session in which you see the problem, use DMAP to list the location of all Frame* files: DMAP Frame o If you see one or more Frame files in a directory _other_ than .../.mctmp/.../ (i.e. a subdirectory of ~/.mctmp) than you need to delete that/those files _after_ exiting your McIDAS session. Since this file may be owned by a different user, you may need to get 'root' to delete the file >the 2nd problem is maybe worse: >when I try to display 2 kind of images, not only one single image, mcidas >never gives me a message and if I look at the processes I see one >corrisponding to the command I typed, and another one "agetserv" that has >the same time stamp, or 1 sec larger. I do not understand this comment, but I betting that the problem you are seeing is caused by the exact same thing as above. The solution is the same, EXIT all McIDAS sessions and delete FrameN.M files from all directories in your MCPATH. >you can find 2 examples of those images @ >http://metsun1.met.sjsu.edu/~leoncini/images/NCAL_010713_2130 >http://metsun1.met.sjsu.edu/~leoncini/images/VIS_010713_0025 > >We are running MCIDAS 7.7 on a Sparc 2.7 machine. > >any clue? Please try the suggestion above and let me know if that does not solve your problem. Tom Yoksas
