Showing database build time as a function of the number of peptides cataloged. The figure shows the time for building a tryptic database against the number of peptides. The data is for a tryptic database with limited modifications. Build times are higher with semitryptic builds or with more modifications. Build times for tryptic digests range from a few minutes, largely representing set up time, to under an hour for the largest databases with over a million proteins.
