Problem with ENVITask BuildBandStack 2364 1
Started by Deleted User
I am trying to stack 2 bands together from 2 different landsat images using ENVITask('BuildBandStack'). These are landsat images from two different years, and Band 1 in both years. When I run my code though a debugging arrow pops up at the ENVITask('BuildBandStack') line of code shown below, and I am not sure why.
The code I am using is:
; Start the application
e = ENVI()
; Select 1st Landsat Band
File1 = 'F:\Sheyenne\Atmospherically Corrected Landsat\Sheyenne_main_clip\LT50300281984137PAC00_...

Can&39;t edit previous multi-line command 2421 0
Started by Deleted User
I'm using IDL 8 on Fedora (gnome). When I up-arrow to the previous command while in command-line mode, I can't edit earlier than the final line if the command is longer than one line. The cursor won't scroll to the previous lines. Is there a fix for this Thanks.

Hi all,
I'm a novice in IDL. I'm trying to extract raw WRF (Weather Research and Forecasting) data which is in NetCDF format using IDL. I compiled the procedure called extract_WRF_surface_grid_D01.pro and then ran it. But I got this following notification:

Plot procedure slow draw time 2094 1
Started by Zachary Norman
When I use the plot command, i.e. plot,x,y, there is a long delay before the plot
appears in the plot window. If I type “window”, then the plot appears right away.
When I use the overplot command - overplot,x,y - it also takes a long time for
the plot to appear. What’s going on and how do I fix it
I’m running IDL 8.4.1 on MAC OS X Yosemite, using the latest version of X11 (2.7.7)
and Terminal.

Tooltips 2297 2
Started by Deleted User
Hi,
Does anyone know if it is possible to display a tooltip when either the cursor is over a cell, or the cell has been selected, in a Widget_Table The reason being that if I have a cell that contains an entry larger than the width of the cell, I would like the tooltip to display the entry, a bit like IE does with its file view.
Thanks

IDL-Java Bridge and Ctrl-c 2218 2
Started by Deleted User
We have an issue with one of our tools that uses the IDL-Java bridge. After using the tool, we find that using Ctrl-c no longer generates interrupts for the rest of the IDL session. (We're seeing this with IDL 8.4 on the command line on Linux and Mac machines.)
After some experimenting, we've found that the following is enough to reproduce the behavior:
(Start IDL)

Interrupt encountered.

Help with Regress.pro or Regress2.pro 2287 1
Started by Deleted User
So i wanted to use Regress.pro. Usually when we fit a data, we have constant and coefficients. Regress has both. However, there is only error for Coefficients but not for the constant. For example, if we have Y = mX C, we have errors for both m and C, or Y = m1 X1 m2 X2 C and the error for m1, m2 and C. Regress doesnt have error for C. I dont seem to understand why we do not have one. Then i moved to Regress2 hoping for a better fit. However, Regress2 doesnt have constant factor and has be...

GAUSSFIT error 2081 4

Hi all, I'm trying to use the built-in IDL function gaussfit.pro, and every time I try, I get the following error
Keyword parameters not allowed in call.
Execution halted at: $MAIN$
I'm only trying to get the function to work right now, so I'm just running the sample code from the gaussfit help file, which calls the function like so:
yfit = GAUSSFIT(x, y, coeff)
This call doesn't even include a keyword parameter, so I'm baffled. I've also tried calling it with keywords set, and I ge...

MRDFITS error 4193 1

I get the following error:'Variable is undefined:MRDFITS' whenever I call the MRDFITS function with the given parameters-variable name of file, extension, header. The variable representing the file as well as the extension value (0) are defined before the function call, and as I understand the header becomes defined as a string array containing file's header after the function call is completed.
Is the MRDFITS simply not defined in IDL version 8.4, or am I not defining the parameters prope...

IDL 8.3 Plot function on Mac causes error: " Internal error: failed to get LUT." 2415 1
Started by Deleted User
--------------------------
IDL User Question:
--------------------------
Hi,
I'm getting an error using the PLOT function (which, I'm new to. I'm accustomed to PLOT as a procedure).
ii = plot( i,A_Correlate( r6, i ), /OVER, COLOR="Green" )
Internal error: failed to get LUT.
This apparently is caused by the COLOR keyword. I've tried giving it other values (e.g., an integer), but get the same error.
The curves are being plotted and with the specified colors, despite the error m...
