simple questions

[rdu]

Hi guys,

I started and got two simple questions:

1. I got a example of initial DNA sequence like
234301 gattggccag cgggaagggc atctcgatgc ccaggacctt gccgtggacg actgtcttca
My question is why there is "23401" as prefix; what's it use?

2. If I want to conduct a function analysis based on COG database, can I download COGnitor and run it locally, or I need use locally installed BLAST to achieve it?

Thanks and happy new year!

The "234301" probably indicates that your sequence is starting at that position in ... something ... genome? chromosome? reference? Normally sequences will start off at base #1 but you may have a partial sequence from a longer sequence.

COG, eh? I haven't used it a long time. As I recall COGnitor was undocumented and hard to install. We ended up installing the COG database and using Blast.

Very helpful! Thanks a lot!
