Subject: [Tutor] vcf_files and strings


 
Hi,


I'm a beginner at Python and would really appreciate some help in how to 
extract information from a vcf file. 

The attached file consists of a lot of information on mutations, this one 
though is just 2 rows and 10 columns (the real one has a lot more rows). 

I want to extract the mRNA ID only if the mutation is missense. These two rows 
(mutations) that I have attached happens to be missense but how do I say that 
I'm not interested in the mutations that's not missense (they might be e.g. 
synonymous). Also, how do I say that if a mutation starts with a # symbol I 
don't want to include it (sometimes the chr starts with a hash).

vcf file: 2 rows, 10 columns. 
   
col 0                         col 1            col 2                  col 3     
         col 4      col5            col6                       
col7                                     col8                     col9
chromosome          position           .                  Reference       
ALT      position          .          some statistics and the ID:s         not 
important        not important

The important column is 7 where the ID is, i.e. 
refseq.functionalClass=missense. It's a missense mutation, so then I want to 
extract refseq.name=NM_003137492, or I want to extract only the ID, which in 
this case is NM_003137492. 

Then I want to do exactly the same thing for all the other mutations, but only 
for the missense mutations not the other ones. How do I accomplish that? Where 
do I start? 

Best,
Anna
