I am trying to blast my sequence against primate databases remotely. But there are so many databases, and most are in abbreviation. Can you explain what they are in the below example list?
chimp AACZ contigs chimp AADA contigs chimp bes chimp est chimp htgs chimp all contig chimp refseq contig
and which one should I use for NGS reads?
It will be good, if you can give more details about what kind of reads you have and what are you going to do with them using blast. If you are going to align reads using blast, then Pierre's suggestion is right. For the databases (as far as I know)-
chimp AACZ contigs
chimp AADA contigs
AACZ and AADA are prefix of accession numbers. Both of them contains sequences from whole genome shotgun and have different entries. Look at this and you can find information for both of them.
chimp est and chimp htgs stands for express sequence tags and high throughput genome sequences
chimp all contig will include all the contigs (different assembled versions and entries) and chimp refseq contig will align against reference sequences only.
