4 Replies and 1066 Views Output to external format ...not closing result  1066  4 Started by  Deleted User Dear all, I seem to have a really minor issue but can't figure out how to solve it. In some codes, I am using envi_output_to_external_format, i.e. as below. The problem is, I cannot really close the output file in Envi. This is not so bad in the classic version where it only appears in the available bands list but in the new version the image is also shown in Envi which is why I am running out of memory for bigger batch processes using the new version. Can anyone tell me how to close the output...

0 Replies and 1381 Views ushort with ncdf_vardef  1381  0 Started by  Deleted User I am writing netCDF files with IDL 8.1 and am encountering a problem when I use the USHORT keyword in calls to the NCDF_VARDEF function. I get the following error message: NCDF_VARDEF: Unable to define variable. (NC_ERROR=-45) If I found the correct interpretation of error code -45, it means it's a bad data type. I don't get this message with other data types such as long integers, floats, bytes, or even signed 2-byte integers (using LONG, FLOAT, BYTE, and SHORT keywords, respectively). I jus...

1 Replies and 1466 Views IDL Workbench broken after Path update  1466  1 Started by  Deleted User Hi all! I am using the IDL 8.2 workbench and included /Applications/ in the IDL Path (in the Preference Section in the IDL Workbench). Since then the IDL Workbench launches, but the buttons (run, stop, break etc.) don't show and the Preference Tab does not open, it's basically not usable. Re-downloading the workbench does not work since IDL 8.2 is not offered anymore and the license my Insitute has purchased has not been updated to IDL 8.4 yet. Is there a way of deleting/editing a preference fil...

0 Replies and 1205 Views Parallelization of image analysis  1205  0 Started by  Deleted User Hi, I am an IDL novice so please bear with me if this question is trivial. I have a piece of code that on the basis of two images generates a new image. I've written a function that for each pixels (i,j) in the input images iteratively solves for the new image value. The way I step through the two images is in for loops (I now this is probably bad...) like below for i=1,dim1 for j=1,dim2 call to function which returns new value of pixel(i,j) endfor endfor My calculation is rather slow (~0.1s...

4 Replies and 1449 Views ENVITask VectorAttributeToROIs Routine Task  1449  4 Started by  Deleted User Hello, I'm working on an task to subset images via roi. And I can't seem to figure out why my Task.OUTPUT_ROI usesage doesn't begin/retrieve the first attribute in the roi. As you can see below when I enter the FOREACH loop I'm setting up the index to begin with index 0, which should be the first record in this case the first BOX. But it does not do this. I'm using shpObj to get the first attribute so I can specify a suffix to attach to the name. Obviously I want these to match but ...

0 Replies and 1233 Views subscript error returns NaN  1233  0 Started by  Deleted User On my development system, a subscript out of range problem seems to return the NaN value rather than a runtime error. This is also true when running a binary on the same system. When I distribute the binary to a user who runs it under the VM, the subscript problem throws a runtime exception and terminates the program. How do I get my development system to throw runtime exceptions in this circumstance I need to find these problems myself so my users don't. I am running IDL 8.2.1 Build id: 2...

0 Replies and 1429 Views Size limits in HDF?  1429  0 Started by  Deleted User I've been converting HDF5 files to geotiff for some time, but one of them causes an error when I do h5d_open. The only difference is this new file is much larger than previous files, about twice as large (8.9 GB) and has dimensions of 8281 wide x 14208 long x 13 dates. I'm thinking the length is too large, but I can't find any documentation describing limits. My system: IDL 8.0, Mac OS 10.8.5, ~60 GB of free disk space. Thanks for any tips on how to deal with this, Tom Farr
