GAUSS2DFIT (bug solution) 44 0
Started by Mike Wong
GAUSS2DFIT with the /NEGATIVE option is supposed to fit a gaussian 'valley' instead of 'peak.' i came across intermittent cases where the function seemed to give a good fit in terms of parameter values, except that the output parameter A&91;1&93; was positive instead of negative. also, the return value had a positive gaussian peak instead of a negative gaussian valley. i have not thoroughly tested this, but adding this line of code seems to fix it: a&91;1&93; *= keyword_set(n...

Contour Function vs Procedure 48 0
Started by Josh Herron
I am trying to plot horizontal scans taken from an aerosol lidar system. The raw data is composed of range resolved aerosol density collected at a particular azimuth angle. The range and azimuth data I convert into values of Northing and Easting against which I plot the aerosol data. If I use the contour plot procedure the data is plotted correctly, but if I use the contour function the same data will generate a qhull error. Is there a difference in how the qhull procedure is called in each ...

IDl bug 198 2
Started by Francesca Scipioni
I use IDL 8.8, and I recently upgraded my OS to Big Sur. After that I notice that, when I press return on the keyboard to go to the next line, the line below disappears. This happens because the process of creating a new blank line by pressing the return key takes a very long time. After a new line is created, the delated line appears again. I also noticed that if I move the IDL window, the new line appears right away. This is a very annoying problem, how can I solve it

IDL 8.8 Workbench, icon sizes (Win10 x64) 156 2
Started by Kip Matthews
In upgrading to IDL 8.8.0 from 8.7.2 (on a Windows 10 64-bit PC), the icons of the buttons in the IDL Workbench (for New Pro File, Cut, Paste, Compile, etc.) are drastically smaller in size than they were in the 8.7.2 Workbench (very problematic on a UHD-resolution monitor). In the 8.7.2 workbench, one could right-click on the toolbar and get an option to show text on the buttons, or to use small small icons; the 8.8 Workbench doesn't provide these options. I don't see any settings in Preference...

Variable undefined problem: STRSPLIT 52 0
Started by Brivael Laloux
Hello everyone, I am a beginner in IDL language and I need it to use the ACIS Extract package. After instaling the IDL and the reauested libraries I tried to do the tutorial example of the package. I had several problems including incomplete IDL_PATH to access all libraries. Anyhow, I couldn't solve one problem: the function STRSPLIT. At some point, a procedure of the ACIS Extract package used this function and it raised an error 'Variable is undefined: STRSPLIT. Execution halted at: $MA...

reading and processing multiple bands into one big file 124 1

Hello, I am helping a PhD student automate processing of hundreds of huge satellite imagery files.

Hi guys, My IDL program stops automatically at regular intervals, about 2 hours, although it can run successfully every time after I restart it. The error message is: Failed to open image.

IDL PRINT format code problem 296 0
Started by Jim Uba
Q: Why does the following fail to print as expected IDL> a1 = 1 IDL> a2 = 2 IDL> a3 = 3 IDL> print,format='(8a,i02,i08,a3,i02,a4)', 'abcdefgh',a1,a2,'ijk',a3,'LMNO.txt' abcdefgh 1 2ijk 3LMNO.txt I expect output like: abcdefgh0100000002ijk03LMNO A: The first format code '8a' is not correct for the desired output. '8a' specifies output for 8 strings. Instead, the correct format code should be 'a8'. For example: IDL> print,format='(a8,i02,i08,a3,i02,a4)', '...

Widget focus 316 0
Started by Jürgen Koglin
Hello, I have several floating draw widgets. All these widgets have the same level hierarchy. Setting the input focus automatically on one of these widgets, when I move the mouse over it, works fine. Unfortunately, 'widget_control, /input_focus' does not only set the focus on the widget, but also brings the widget to the front. How can I set the input focus on the draw widget without bringing it to the front Which means, if applicable the widget should stay behind the others and not be pu...

how to access AWS from IDL 219 1

I searched around, but was not able to find anything especially useful as far as examples or documentation on how to access AWS datasets from within IDL. In particular, I would like to get satellite data from GOES-16 and 17: https://registry.opendata.aws/noaa-goes/ Any hints or leads would be greatly appreciated! Thanks, Brian

Interrupt embbeded Java Thread with CTRLC 412 1
Started by IKhokhriakov
Dear L3Harris Forum, I have a question concerning using embedded Java processes into IDL (Java-IDL bridge). Specifically I need to catch and process CTRLC while executing long running Java process from within IDL. Just listening for Thread.isInterrupted does not work. The source code of the embedded Java library can be found here: https://github.com/hzg-wpi/idl2tango/blob/6e8cd9f1a340481f7505f23d1a1c39cb36e493dd/src/main/java/hzg/wpn/idl/PollDevStateAwaitor.javaL54 Thanks in advance.

multi-thread warning command line? 326 0
Started by Wouter Schellekens
Hi All, Recently, I've been getting this warning when I run a script from the command line (not from within the developer environment): OMP: Warning 190: Forking a process while a parallel region is active is potentially unsafe. Quite often the script will hang and not finish when this warning comes. It sounds like there's an issue with multi thread processing, but I'm not sure. Anyone have any good ideas on this issue and how to solve it I'm running IDL 8.7.3 on x64 Debian GNU/Linux ...
