I need to peak pick and align about 250 samples, and because I forgot to turn off Microsoft's automatic updates, the computer I had set up to do this restarted right in the middle of the xcmsSet step, and I lost about a day of computing time. Lesson learned: I turned OFF automatic updates. However, it made me wonder whether there was some way to save an xcmsSet object that's only partway completed. Is that possible? Could I, for example, run xcmsSet on a subset of my samples, save what I've got so far, then run xcmsSet on the next chunk of samples, save again, etc. and at the end, put everything together into one xcmsSet object?
Many thanks in advance for any help! You guys are great!

Hi,
yes, you can
xsall <- c(xs1, xs2)
check "? c.xcmsSet"
Yours,
Steffen
Combines the samples and peaks from multiple 'xcmsSet' objects
into a single object. Group and retention time correction data are
discarded. The 'profinfo' list is set to be equal to the first
object.
Well, that sounds almost too easy! Thank you very much, Steffen! I'll give it a try!
