Hi all,
I'm trying to use taverna, but I'm a little bit lost in the workbench about how 
to find the right tool. For example, one common task I'd like to perform would 
be:

+ open a tab delimited file
+ 'grep' for the SNPs ( lines containing the regex rs[0-9]+ )
+ 'cut' the 'Xth' column containing the SNPs
+ find the positions of those SNP on a given build of the human genome ( using 
the mysql anonymous server of the UCSC)
+ find the distinct Genes overlaping those SNP ( again, using the mysql 
anonymous server of the UCSC)
+ output the result to a file

Can anyone help ? I would be interested in how you find the right nodes and how 
you fill the information.

Thanks in advance

Pierre
