Sounds like a good idea - and it shouldn't be to difficult. Let me know if you need some help or something is unclear @jmorim
Regarding addon for `CAMERA` - if possible I would like to keep this 2D grouping independent of the classes in `CAMERA`. I would like to have a more general, modular...
Totally understand that. I suggest you create a grouping function that takes standard R data types as input (such as numeric, etc) instead of a specific S4 class. That way...
Hi @davidgarciam ! Now that's an error I have not seen before. According to the error message the spectra in (one or some of) your data files are not ordered...
Just a note: in principle it *should* also be possible to sort the spectra in the `OnDiskMSnExp` object (i.e. your `raw_data`).
Regarding how to sort, I can help there, but we might first want to ensure that the input data is correct. As @sneumann points out, how can you have retention...
hm, note that along with `xcms` you'll need also to install R and a large number of Bioconductor packages - not sure if your IT department wants to check all...
This problem might have been fixed in the *new* user interface. I've rewritten and simplified the obiwarp function for this new user interface. The new interface is based on classes...
Personally, I'd like users to perform a differential abundance analysis using tools that are available outside of `xcms` (e.g. using the `limma` package, or *plain* R functions) - one simply...
One thing you could try is to call `xdata
