fDesc[0] = "The GPMAW program is primarily intended as a tool for mass spectrometric analysis of proteins and peptides. However, a number of other bioinformatics tools have been included, so the use of the program extends far beyond simple mass analysis.<br /> <br /> Main features:<br /> <br /> - Sequence handling: Import of sequences from a number of different formats with direct database search in Entrez and in local databases (FastA format and Swiss-Prot). Sequences can be saved in local files (databases) for future reference.<br /> From the sequence window a large number of actions can be performed. Sequences can be exported in FastA format (either singly or all sequences at once) for easy transfer to other programs.<br /> - Mass analysis: The protein can be cleaved by automatic methods (e.g. a flexible nomenclature for defining enzyme actions) or manually. The peptides are displayed with a number of parameters (various mass values - mono, ave, charges - Bull&amp;Breese index, HPLC index, pI, charge) and can be further worked upon (e.g. cross-linked, new cleavage).<br /> Peptide mass searches can be performed on any local database in FastA format.<br /> - Bioinformatics: A number of graphs can be displayed, hydrophobicity, dot-plot, secondary structure prediction. BLAST searches can be performed on local databases. Multiple alignment using ClustalW.";
