importing normalized cel files in to geworkbench

Question

[nazaninhoseinkhan]

Dear all,

I am new in working with geworkbench software. I want to import cel files in to it. First I normalized 12 cel files with affylmGUI in R. When I try to import this normalized file in to geworkbench I receive an error message. I tells me that the number of columns in the first line must be 12 while it is 13. It suggests me that I have to manually insert a tab in the beginning of the first line. Unfortunately even after inserting tab I receive the same error.

Can anybody advise me how to solve this problem?

Regards

Can you paste the first line here ? Can you check the number of fields with awk ?

awk -F"\t" '{ print $NF}' filename | head

Hi

Thanks for your reply. I could find the solution. The first column(gene names) did not have any label. When I added "ID" label to this column, geworkbench could get it.
