0 bytes in sample data file and trouble converting excel

Hi Ralf,

XCMS looks pretty outstanding and I can't wait to use it. Congratulations on y'all's work.

I am just getting started using XCMS and am trying to find the best way to get started. For some reason, every time I try to download the pepsi cola data set, it indicates that 0 bytes were contained in the download file.

I'd skip this step, however, I was trying to get an idea of what the input data set should look like. I'm trying to find a way to convert the raw data that I have now that has peak areas contained within an excel spreadsheet. Based on what I've read the conversion formats seem to be from data output from GC/MS or LC/MS etc. But I did not carry out the tests myself I simply got a .xls spreadsheet of the results from LC/MS.

What do you think could cause the sample data not to work properly and how do I go about changing my excel spreadsheet into an acceptable input form?

Thanks,
