1
metaXCMS / Common features
Importing files in metaXCMS and filtering is no problem, but when I try to find the common features (with m/z tolerance 0.01 and retention time tolerance 60s), no Venn diagram is shown and the following message appears in R:
Error in function (x)  : object 'CommonFeaturesTab.continue' not found
What can I do about this?
2
metaXCMS / Alignment + EICs
When I want to align my data or produce EICs with metaXCMS, nothing is happening. In R an error message appears:
Error in xcms:::phenoDataFromPaths(files) : Directory tree must be level
What can I do about this?
