 just for me

hey, i am a computational biologist, this group sounds just right for me! So let me write the first comment :) My favourite scientific linux apps:

-gnuplot (plotting data)
-pymol (visualising proteins)
-kalzium (periodic table of elements)
-bkchem (drawing chemical structures)
-clustalw (multiple alignments)
-latex + kile (writing papers or thesis, drawing formulas)

else, most programs i use are written by myself ;)

chemdraw is better than bkchem, I miss it on linux. Sigma plot is great too, would also be nice to have this on linux. Apart from those, I could never imagine doing scientific work on another os!

I prefer to use mathgl (http://mathgl.sourceforge.net/) for drawing. It's more flexible and the pictures look much smarter.

As for visualizing molecules, I like VMD the most.

Physics is like sex. Sure, it may give some practical results, byt that's not why we do it.

Thank you for the MathGL Tip, it looks very interesting, and I didn't know about it :)

VMD is a great viewer too, it makes very beautiful pictures. But I got used to pymol since so long...

cheers!

 Simulation software

I am interested in digital communications and related software applications. I have extensively used IT++ library as a free replacement for Matlab. Unfortunately IT++ lacks graphical capabilities and Octave has limited capabilities wrt Matlab.
I would like to have a tool to graphically represent the trellis of a convolutional code, given the generator polynomials. Do you know such a tool?

I tend to use Matplotlib, as it is pretty much equivalent to Matlab when producing plots. However, I don't know about your specific plot type....

I have forgotten to mention: it is possible to load results from IT++ into Matlab or Octave, while in matplotlib I don't know how to do it. Without some API for loading results from another app, this plotting tool is not too useful.

I guess the point i was trying to make is that python+scipy+numpy+matplotlib+etc is roughly equivalent to Matlab or Octave, but with a nice programming language ;D

Additionally, scipy is able to read matlab files (I guess that with some limitations): http://www.scipy.org/doc/api_docs/SciPy.io.mio.html

look at mathgl. It works with octave, rather simple and makes smart graphs.

Discrete Geometry 3D Viewer

I have written Discrete Geometry Viewer which handles 3D/2D/1D plots and does convolutions. You can find it on this site.

 Linux related thesis

Just wondering: are there thesis proposals (PhDs) working on issues related to Linux ? For example, I have begun to use KDE4.3 and I am quite astonished by the level of complexity already achieved: one can define activities in top of desktops, etc. Desktop usability issues requires quite a research IMHO.
