[galaxy-user] SAM Tools Pileup

Hi,

I'm having trouble with the Generate Pileup tool and hope that you could help me troubleshoot this. I ran the tool successfully with the following options:

* Use built-in index * Print the mapping quality as the last column * Print all lines * Cap mapping quality = 60 * Call consensus = yes, then default parameters

The reference bases of the entire pileup file, however, are all "N." I double checked and the all the files have the same reference genome (mm9). Do you have any ideas on what went wrong?

Thanks very much for your help,

Kathy
