BlastP simply compares a protein query to a protein database. You pack up a new BLAST database and use Cancer_NT_Jan_2016_Rev_1 as its name, to avoid confusion, and then tell anyone what happened. • BLAST assesses the statistical significance of high- scoring databases matches• For each alignment between the query and a database protein, it calculates an E-value• E-value: the number of database matches of a certain alignment score expected by chance, in a database of the size searched• The lower the E-value, the more significant the alignment score for the sequence match … Mask any letters that were lower-case in the FASTA input. The BLAST database files can then be extracted out of the resulting tar file using the tar utility on Unix/Linux, or WinZip and StuffIt Expander on Windows and Macintosh platforms, respectively. Enter one or more queries in the top text box and one or more subject sequences in the lower text box. You can also create a custom database.
