Hi David, I did: sudo apt-get remove g77 sudo apt-get install gfortran before starting the whole thing, so I assume that should take care of it. I am not sure how much I actually depend on Atlas for what I do, so your advice is well taken. One thing I can think of is PCA and ICA (of *big* matrices of float32 data), using the MDP toolbox mostly. I should find out in how far Atlas is crucial specifically for that.
