The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. Installation instructions are available for Windows and LINUX/UNIX. I installed psipred according to instructions: cd psipred/src make make install And this seems to work fineThe procedure PSI-BLAST uses can be summarized in five steps: (1) PSI-BLAST takes as an input a single protein sequence and compares it to a protein database, using the .PSI-BLAST allows users to construct and perform a NCBI BLAST search with a custom, position-specific, scoring matrix which can help find distant evolutionary relationships. How to perform a query against a precomputed database of sequences. blast基本原理很简单，它的要点是片段对的概念。所谓片段对是指两个给定序列中的一对子序列，它们的长度相等且可形成无空位的完全匹配。 图 1-a 中方框 .04 but cannot get PSI-BLAST to work.
