MoBIoSFound is an implementation of a peptide mapping program similar to ProFound. It replaces the first part of ProFound's algorithm with a database lookup of peptide mass fingerprint spectra (using MoBIoS metric-space indexing), then uses ProFound's sophisticated Bayesian algorithm to probabilistically rank the hits.

Please email smriti AT cs DOT utexas DOT edu if you experience any problems using MoBIoSFound.

MoBIoSFound2, an extension of MoBIoSFound, identifies proteins via database lookup of peptide fragmentation spectra (MS/MS or tandem MS). It uses MoBIoS' metric-space index as a coarse filter, where any fine ranking method can be applied to the output of the coarse filter; we use ProFound's Bayesian scoring scheme. The index also uses precursor mass information to increase the specificity of the search. Details on the index and our experiments can be found here.

Please email smriti AT cs.utexas.edu if you experience any problems using the MoBIoSFound demo.
