Hi Maura, First of all, it seems from the IDL website that Linux is supported! (They're coy about their pricing, though ... ) Next, looking at the functionality of IDL, I think (without checking in detail) that a great deal of the IDL functionality of operations on arrays can be found in octave: see http://www.octave.org Octave also has a well-developed set of libraries for the range of signal analysis operations described for IDL. However, octave's repertoire of "main-line" statistical analysis routines is somewhat limited: a good bit of basic stuff is there, but not much of the fancier procedures. Also, while octave can handle image analysis up to a point, I'm not sure that it can match what IDL claims. Octave has quite good data graphing capabilities but again, I think, does not go as far as IDL seems to. Finally, if you need access to really comprehensive statistical analysis, you should have a look at R: http://www.r-project.org R also has very comprehensive array procedures (and lots of other types of complex objects too). However, I'm not sure what you can find there for image analysis (but this is mainly because I don't have much to do with that area). There are hundreds of extra libraries for R and it may well be that somewhere in there are useful image analysis resources. Also, there are some specialist groups using R who develop their own techniques, and there may be an image-analysis group developing useful stuff. Whatever the case may be on this front, there's no doubt that R has the capability to support anything you might want to do with images -- it only needs someone to implement it! I hope these commments are useful.

Not sure but maybe R-project is what you are looking for. (www.r-project.org) It's extremnly powerfull and mature. It is also cross-platform. (Linux, Windows, Mac, ...) --- Maura Edelweiss Monville escribió: > Is there a library or development environment

equivalent to IDL (http://www.floating.co.uk/idl/) supported by Linux/SuSE or Linux in general ?

I'm particularly interested in BioMedical Imaging development. I'd rather discard any package that runs on top of Windows !!!

Thank you very much.
