IDEOM[248] filters and detects peaks based on XCMS[13] and mzMatch.R[249], enables noise filtering based on [249, 250] and allows for database matching and further statistics.
As above, the C data were more useful than H for database matching.
Confident peptide identifications were determined using these stringent filter criteria for database match scoring followed by manual evaluation of the results.
Peak capacities were determined from selected extracted ion chromatograms, and tandem mass spectrometry data were used for database matching using the MASCOT search engine.
Tandem MS fragmentation of the peptide generated a set of tandem MS ion fingerprint data, which was exported for database matching and subsequent identification using the Mascot program (Matrix Science Inc ,Boston, MA, USA).
Searches of the rice genome at The Institute of Genomic Research TIGRR) [ 39] for Interpro Database Matches by five different methods including HMMPfam, HMMSmart, BlastProDom, ProfileScan, and superfamily were carried out.
To identify EF-hand-containing proteins, firstly, we functionally searched the Oryza sativa L. genome at The Institute for Genomic Research TIGRR) [ 12] for Interpro Database Matches by five different methods including HMMPfam, HMMSmart, BlastProDom, ProfileScan and superfamily as described in the "Methods" section.
Studies by Dalby and Birkett [ 35] and Joshi et al. [ 36] have also demonstrated the benefits of database matching for identifying compounds present in smokeless powders.
The closest database matches for these markers after three psi-BLAST iterations (pBLAST search of translated marker sequences against nr, cutoff E-25) are detailed in supplementary table S9, Supplementary Material online.
On the other hand, prospective researchers looking for a database matching their research question/idea can do a variable as well as a categorical search.
