Affinity Propagation Clustering

The affinity propagation algorithm takes as input a set of pairwise similarities among compound fingerprints, considering them as potential representative compounds (exemplars). The clusters and their corresponding representative compounds are calculated by exchanging messages between data points until a maximization process converge. Thus, exemplars for each cluster are proposed to the researcher for further investigation.

Step 1.
Please, Upload files* in ".sdf", ".mol", or binary fingerptint in ".txt" format.

*Warning:
Uploaded filename should not contain any special character i.e. @%$_^.-~
Files are temporary saved on the server and deleted after processing.
Maximum allowed upload size is 10MB (~2000 compounds).
fingerprint .txt format should contain two parts separated by a comma (,) character, the binary fingerprint and the name of the compound i.e:
00000110000001010000111101100000000000001111111111111110, Compound 0001
00111111111111111111000000000000000000110111000000000000, Compound 0002
01011110011001000110100100101011101110000000101111001101, Compound 0003
Binary part should not conatain any space before comma.
