Simple question on path 1328 2
Started by Deleted User
Hello,
I am compiling running an ABC.pro in a given Linux directory. ABC.pro calls other procedures, lets say 123.pro, which are located in the same directiory as ABC.pro. At run time, I get an error saying that the '123' variable is undefined.
How can I solve this problem I went ahead and opende the 123.pro and compiled, then went back to my ABC.pro and it went well. How can I avoid the manually compiling 123 (or other procedures needed by ABC.pro) on the fly
Thanks!

read HE5T_NATIVE_INT8 data type from HDF5 file using IDL 1180 0
Started by Deleted User
does any one have experience about how to read HE5T_NATIVE_INT8 data type from HDF5 file using IDL. When I use HDFview to open the file, the missing data is filled with -127, but after I use idl to read the data, all the missing data is filled with 0, which is a problem since valid data range is 0-100.

Hi all
My name is tamir a PhD student on the cross road of marine biology and remote sensing.
I’m currently looking for someone with IDL knowledge to write a short code for a procedure I’m trying out. Is short and shouldn’t take long to undertake.
If anyone wants to rise to this challenge (massive favour for me) please contact me at the below address.
Many thanks for listening.

On-the-fly color table changes 1308 1
Started by Deleted User
Sorry if this is a FAQ, but I haven't been able to find an answer.
We have old Solaris systems here, which have a lovable feature of allowing color table changes to immediately, on-the-fly, affect the color of images. For example, one brings up an image in IDL, then runs xloadct. Changes to the color table using xloadct sliders immediately affect the colors in the image. I supose this is because of the old 8-bit pseudocolor visual.
Is it possible to achieve this with newer X Window Syst...

AVL Binary Tree Implementation? 1201 1
Started by Deleted User
Hey there, I've searched but haven't found anyone yet who has implemented algorithms for working with AVL binary trees in IDL. I was wondering if anyone out there in the community has done so and would be willing to share, or if there's a better way through hooking IDL to an external AVL tree library, etc.
Thanks very much for any ideas or tips.

Global Curve Fitting 1509 1
Started by Deleted User
Does anybody know if it is possible to fit multiple data sets simultaneously in IDL. I am currently using 'curvefit' to sequentially fit 3 datasets, but these datasets influence eachother, so I am looking for a more appropriate function. It is basically a 3 compartment model, with interaction from one main compartment with the two others, but the two others do not interact. I have time varying data for all 3 compartments, and I want to fit the kinetic parameters of the 3 compartment model wit...

Simple question: Vector Fields and the length of corresponding vector arrows 1491 1
Started by Deleted User
I am working on a project in which we would like to compare IDL generated vector fields based on their magnitude, but the magnitude(represented by length of vector arrow) of each vector visually depends upon the maximum magnitude in each dataset.
This is a problem because on one vector field a value of 20 could be the longest arrow (fi highest magnitude in set), but on the next vector field only be half the maximum size (if the magnitude max was 40, for example).
Is there a way to set a f...

How to calculate FWHM of 3D image 1357 0
Started by Deleted User
Hello, I am working on 3D image processing and caculating the FWHM (curvefitting).
But some times, I cannot get the 'good ' results, for example, the voxel size is 1.3*1.3*1.3 mm^3, but for some points in the image, the corresponding FWHM is 1 mm. It isn't right.
How can I deal with that. thanks

Is there a way to read in a string, use it for a variable name, and then refer to that variable name inside IDL I see that there is a function IDL_VALIDNAME that can tell me if a string can be used for a valid IDL varibale name. However, once this is validated, how do I use this string as a variable

In some others ocassions a different error message apears:
