Dear Galaxy community,

I’am new to the Galaxy project. I tried using the Volcano plot tool. Everytime I got th efollowing error message: [1] “Header row detected”  
Error in log10(pvalue) : non-numeric argument to mathematical function  
Calls: print … → f → sca

Does anybody knows what to do? I’am not familiar with bioinformatics or programming and really do not know what to do.

Thanks in advance.  
CS
