I did an analysis of a protein on AUC and did a sedimentation velocity and equilibrium experimetn. after acquiring the data, I stored in in a USB stick and tried to run it on Sedfit. I'm currently using a MAC and I've isntalled parallels onto the PC just so its easier to use sedfit to analyse my data. when I upload my files onto sedfit (120 runs) the program crashed and closed. it doesn't do that when I only upload 20 runs though... any ideas?
