Did you move raw data or results after XCMS processing ?

I did XCMS online and downloaded the results. And the raw data are in the same folder while I was doing XCMS online. Now results are in separate folders as I wanted to compare 3 sets. So 3 different folders for 3 results. And raw data are in different folder. But its in the same folder while I was doing XCMS online.

Thanks

At the moment, metaXCMS is not compatible with the results produced by XCMS online.
We are in the process of integrating metaXCMS into XCMS online.

For now you can run XCMS and metaXCMS as described here:
Meta-analysis of untargeted metabolomic data from multiple profiling experiments (http://http://www.nature.com/nprot/journal/v7/n3/full/nprot.2011.454.html)

But XCMS online provides results that can be downloaded and which are compatabile with meta-XCMS. Like XCMS provides data in .csv and .tsv format which are easily read by meta-XCMS. Its only the raw data that are not recognized/assigned by meta-XCMS. But will do go through the paper which you have provided.

Thanks
