Applying Decision Trees to Image Files systematically, IDL script 1146 0
Started by Deleted User
Hi,
I have a multitude of image files that I am attempting to apply a decision tree to.
I have created the decision tree to analyze the images, but am looking for a way to apply the decision tree to my images and retrieve the output.
In envi I can do this one image at a time simply through the envi interface, but I was wondering if anyone could provide me with the commands for IDL that could access the bands my images have in envi and then apply the band math to the images a...

fail to launch 'Preference' menu in IDL 8.0.1 DE under Mac OS X 10.7.2 1378 1
Started by Deleted User
Hi all,
I am using IDL 8.0.1 under Mac OS X 10.7.2 Lion. In the first 2 weeks the Preference dialog box in the IDLDE worked well, but one week ago it suddenly failed. Neither clicking the 'Preference' button in the 'IDL' menu nor using the shortcut 'cmd,' could launch the preference dialog box. So now I can't modify properties of the developing environment and IDL itself. I tried restarting the IDLDE, IDL and rebooting the computer but the problem is still there.
Anyone to share ...

Map Projection Bugs Cause Errors 1204 0
Started by Deleted User
Readers of this forum who don't keep up with the active and extremely useful IDL newsgroup (comp.lang.idl-pvwave) may be unaware of two recent developments with map projections that can cause inadvertent errors in your programs.
First, there is a bug in all versions of IDL up through 8.1 that causes a UTM map projection using the WGS84 ellipsoid as the datum (the most common ellipsoid to use with this projection!) to produce incorrect results when coordinates are being translated from la...

License server issues using a VPN connection 1611 2
Started by Deleted User
I'm at a university which has an IDL license. Normally, a VPN connection allows me to use University purchased tools off campus. I'm having trouble doing this with IDL. I believe it is an allowed option to do this.
I'm using Cisco's AnyConnect VPN client. Does anyone know if there are additional configurations that are needed to allow this setup to access the license server
thanks in advance,
Tom

Plotting Gaussian with one fixed parameter 1114 0
Started by Deleted User
Hi,
I'm using the Gaussfit procedure to plot a Gaussian to line spectra.
However, IDL is picking the wrong peak to plot a Gaussian to.
I want to specify that the peak is at 0, (so something like a&911&93=0 presumably) but I don't know the other parameters. How can I specify one parameter without specifying them all
On a related note, I also want to plot an absorption Gaussian on top of an emission Gaussian. How would I do that
Thanks
