I have noticed a fair amount data loss and have been searching for the source of the INTERPOLATE command within the IDL library with no success.

2 Replies and 2187 Views IDL memory problem  2187  2 Started by  Deleted User Hi, I've recently installed a software package for idl 6.0 on my Mac (OS X Tiger 10.4.1). The package often spawns new shells. At one point I get the following error message: Unable to allocate memory: to expand environment. I've been searching on the internet for the meaning of this message, but haven't been able to find anything, except for one Windows related problem. Does anyone know what the source of this error (message) could be Cheers, Jeroen

0 Replies and 1706 Views MNF and masks  1706  0 Started by  Deleted User I've built a mask that surrounds my region of interest, then use the mask within the MNF application to zero out those masked areas and force the application to only consider my ROI. This works fine and the MNF results show that the masked areas have values of 0, while the ROI has distinct positive or negative values. However, when I invert the MNF, choosing only the bands I want, the result gives an image that has a spectral profiles for those regions which I had previously masked - thought tha...
