what does the list of snp130.txt mean?

[dzmtnvmt]

hello, everyone!
I am a new comer here.
I've downloaded the snp130.txt from the http://hgdownload.cse.ucsc.edu/golde...hg18/database/
each line is as follows:
585 chr1 259 260 rs72477211 0 + C C A/G genomic single unknown 0 0 unknown exact 3
Do you know what does each column mean?


and I am using the SOAP software doing the snp annotation,and the dbsnp.txt is need. (which looks like: chr1 201979756 1 1 0 0.161 0 0 0.839 rs568
.columns mean: name of chromosome, coordinate on the chromosome, whether the SNP has external allele frequency information (1 is true, 0 is false), whether the SNP is a validated dbSNP (1 is true, 0 is false), whether the SNP is actually an indel (1 is true, 0 is false), frequency of A, frequency of C, frequency of T, frequency of G, refSNP ID)
And what should I do with the snp130.txt?
thanks

On UCSC homepage (http://genome.ucsc.edu) you'll find the TABLES menu at the top of the page.
In the tables menu you select group: Variation and Repeats
and track: SNPs130 and table: snp130
Next to the table selection you can click on describe table schema. It giives you a clue of the table which underlies your dbSNP130.txt file.
it is
<bin><chromosome><chromosome_start><chromosome_end><SNP_rs_number><score><strand><refNCBI><refUCSC><observed_alleles>etc.

Hope this helps,
Peter
