I've got some MDE-polyacrylamide electrophoresis gels in which bacterial ITS
have runned.
I've acquired these gels and then I've created a matrix in which coloumns
represent samples and rows represent each band I could find in the gel with
its relative intensity
i.e.
A B C
1 12 0 13
2 10 14 1
3 0 0 21
....
0 means no band.
Now I have to perform a PCA but I haven't an appropriate software. Does
anibody knows such a software? Possibly freeware.
I think it should be similar to a genomics/proteomics software (the samples
represent bacterial communities under different growth condition), because
of its ability to analize different pattern in different conditions...
