As the swiss say. At the very end one or two amino acids look out of the box into the botomn again in 1 run especially.

Well I trust the results except one or two points. The means stay the same between the mentioned points, but the STDDEV and STD error double, as it is 2000 points or so, it just looks like a smooth curve with a linear (really leanear) spike. I dont thinks its that big an issue though comparativly, as one does not loose the overall curve reguardless.
Thanks for your advice, suggestions and knowledge base.
