Hi all,
I'm working on analyzing sequence base on UCSC genome database and it's
really helps a lot. And I have 2 simple question now.
1. In refFlat table of hg18, some mRNA have multi-records. For example,
NM_001105662 have 9 records. They have different location on the same
chromosome. I compare the sequence of those records, they are similar.
But my research need to know the conservation score for each NT and
they are different among different records. How can I decide which record
should I use for NM_001105662?
2. There are some strange chromosome such as chr22_h2_hap1, chr6_cox_hap1,
chr21_random and so on. So I want to know what these chromosome mean?
And if a mRNA can be found on regular chromosome as well as on these strange
ones, can I think the one on the strange chromosome is less important?
Thanks
Hui
