Regarding Crocker and Grier's particle tracking code 1442 0
Started by Deleted User
This question is more directed to those who are familiar with the 'feature' function developed by Crocker and Grier. The code is located at:
http://www.physics.emory.edu/7Eweeks/idl/kit/feature.pro
I've been trying for some time now to develop a similar code that can be used for particles with a large size distribution. I haven't been able to find a way to modify the feature code to work for such a system, and I'm hoping someone might have a suggestion. The code uses a parabolic mask to con...

Plotting blocked dataset 1424 1
Started by Deleted User
I'm a complete novice to IDL, and would appreciate someone's input how to create a plot using the dataset that I'm dealing with. I have a dataset which looks the posting below. Each block of data contains 20 lines (as indicated in field3), and there are about 5000 blocks. I'm interested in plotting Field2 vs Field5 for each Field3 value. I just don't know how to read my ascii file into IDL array when trying to skip 20 lines for each block. Any help will be greatly appreciate it. Thank you.

Has anyone tried to run JAFROC stats program on IDL VM I keep getting error message
'file not found or not a valid file....'
Could this be because the JAFROC Analysis.sav file was written for an older version of IDL
Any ideas

Working Directory 1289 1
Started by Deleted User
I have just upgraded to IDL 7.0. I am working on Windows XP Pro. In previous versions, if I clicked on a .pro file in a directory, IDL would fire up and it would make the directory in which the .pro
file was located the working directory. This no longer seems to function this way., In IDL 7.0,
when I click on a .pro file, the working directory is some fixed, directory located elsewhere. Ive looked through the documentation, but can seem to find a setting that will set the working directory to...

My program stalls when I dont use breackpoints in IDL 1341 0
Started by Deleted User
I've done a function that estimates a mixture of gammas to fit some data that I have.
This function is executed several time inside a cycle.
If I run IDL with breakpoint (one for each cycle) it works but if I run it without breakpoints the program stalls (stop responding). I left it running during one day (much more time than it should need to execute) and my program didnt finished.
I know that this is a bit strange.. but anyone got the same problem
Best regards,

Does anyone have ENVI/IDL code that performs fully constrained (sum to 1 and abundances between 0 and 1) spectral linear unmixing The unmix_doit procedure in ENVI only incudes a sum to 1 constraint (whereas abundance values can be both negative and well above 1).

capturing error messages while in IDL execution mode 1028 1
Started by Deleted User
Hello,
Is it possible to capture an execution error (lets say IDL encounters a typo or something like that) and send it to a GUI Currently if IDL encounters something it automatically displays some error message on one of the lower windows in the IDL development environmen. I would like to capture that same message and send it to a GUI or a message_dialog box. I looked at the 'on_error' function but did not find what I am looking for.
Thanks!
