I FTPed the image in question down to my machine here in Boulder (running McIDAS-X Version 7.8), and I had no problems in displaying, navigating, or interrogating the image with IMGPROBE. Given this, it sounds like the calibration module for Meteosat data needs to be updated on your system (there have been mods since you originally installed 7.7). >I invite you to log onto Cirrus and see if you can make IMGPROBE >return a IR temperature for AREA9010. OK, I logged onto cirrus and tried to see if I could figure out why I can't compile and link McIDAS. I transferred over a new gcc compiler distribution and some other shared libraries (under the mcidas account), and verified that I can run the compiler on individual files with no problems. The build of the entire package, however, still fails, and the failure is apparently associated with the bash shell executable. The only way we can get around this is to try and replace this executable (in /bin/bash) with a new one. The problem here is that you have to be 'root' to do this, and I do not have root privilege. I could try replacing /bin/bash to see if I can get compilations working and then rebuild 7.7 with Meteosat calibration modifications if you could give me root logon to cirrus. Baring than that, you will need to get a system administrator type there to look into the problem. >Thank you! Sorry I wasn't able to simply jump onto cirrus and get things working. The fact that DSSERVE didn't work (couldn't define datasets as per previous emails) and I can't get the build to work indicates that something has happened on cirrus. I worry that this may be an indication that cirrus was hacked into at some point, but I can't tell if that is true or not.

Tom: Thanks for looking at our MetSat image problem. I'll get you root privilege on Cirrus ASAP so you can get our McIDAS installation on Cirrus able to completely analyze Metsat images.
