Dear Sir/Ma'am

I am interested in PCA calculation for the my wild type protein. I had gone
through the tutorial (http://www.amber.utah.edu/AMBER-workshop/London-2015/
pca/) and prepared this cpptraj script.

My problem is that in 2D PC1 and PC2 image they have coming -250 to 70. I
am suspect that the projection on X axis is very negative.
Could you give me some comment why it showing negative or something i am
doing is wrong.

Best Regards
