nr好像是蛋白质数据库，而且它不含相同序列的。
看过RefSeq吗？是non-redundant的

不知道你这句话怎么来的“但缺点就是这些列表中的序列并没有合并成单一文件存放在NCBI服务器上 运算起来十分缓慢 也就是说blas ...

我做的是tblastn 所以是核酸数据库 nr在这里指Nucleotide collection(nr/nt)
nr: All GenBank + EMBL + DDBJ + PDB sequences (but no EST, STS, GSS, or phase 0, 1 or 2 HTGS sequences). No longer "non- ...

我记得nt是DNA库。
“因为得到的blast结果中的database后面跟的是很长一段的字符串 而单一文件是只有一个数据库的名字而已” 有例子吗？...
