- download: The FP(Frequency Profile) matrix
Results
MDS
- Procedures
- build a pairwise distance matrix (11,912 x 11,912) from the FP matrix (1,137 x 11,912) - euclidean distance
- do MDS (multidimensional scaling) of the distance matrix
- get coordinates from the first three dimension and plot them in a 3D-space
