I have done a couple research jobs in Bio-informatics and I have used Matlab for them. Matlab had a lot of powerful tools and was easy to use. I did thinks with genome sequencing and predicting metabolic pathways. I am wondering what other people think is best? or there might not be one specific language but a few that lend themselves be...

Hi, I'm running Matlab R2009b on Snow Leopard, and I am trying to create a transparent polygon. The following line works fine: figure,fill([1 0 0 1],[-1e-9 -1e-9 1e-9 1e-9],'r') But when I set the transparency, alpha(.5); the figure collapses in on itself. That is, any title, xlabel, and ylabel I have in th...
