Computation times in seconds for search of 80 unmodified spectra against different databases using a single process Intel Core i7-3770 CPU @ 3.40 GHz.

aTarget: database of 236 neuropeptide sequences; K103: k-permuted decoy database size of 236,000 peptides; K104: k-permuted decoy database size = 2,360,000 peptides; K105: k-permuted decoy database size = 23,600,000 peptides; K106: k-permuted decoy database size = 236,000,000 peptides. Computation times in seconds for search of 80 unmodified spectra against different databases using a single process Intel Core i7-3770 CPU @ 3.40 GHz.aTarget数据库：收录236条神经肽序列的数据库；K103：k置换诱饵数据库，肽段规模为236000条；K104：k置换诱饵数据库，肽段规模为2360000条；K105：k置换诱饵数据库，肽段规模为23600000条；K106：k置换诱饵数据库，肽段规模为236000000条。采用单进程Intel Core i7-3770 CPU（主频3.40 GHz），针对不同数据库检索80条未修饰质谱谱图的计算时长（单位：秒）。
