SIMS - Sequential Interval Motif Search

SIMS (Sequential Interval Motif Search) is a software tool design to perform unrestrictive PTM search over tandem mass spectra. In other words, users do not have to characterize the potential PTMs. Instead, users only need to specify the range of modification mass for each individual amino acid. Interally SIMS uses a database search algorithm, thus it requires a protein sequence database in fasta format and a mass spectrum as input.

SpecCons: a java program to generate consensus spectra variants for clustered MS2 spectra

It is widely accepted that consensus MS2 spectra can potentially improve peptide sequencing. Nevertheless there are different ways to generate consensus spectra after MS2 spectra are clustered. To alleviate such problems, this tool (written in Java) is capable of generating multiple consensus variants, depending on user's criteria. Our study has demonstrated that that combining search results over these variants leads to improved accuracy and reliability of De Novo sequencing.
