Hello,

I recently start to use xcms for GC-MS data processing. When I used the example package "faahKO" with the instructed commen line everything worked. However when I try to use my own mzXML file, R studio gave me this error

 

> cdffiles
[1] ".//Control/BE-C1.mzXML" ".//Control/BE-C2.mzXML" ".//Control/BE-C3.mzXML"
[4] ".//Drought/BE-D1.mzXML" ".//Drought/BE-D2.mzXML" ".//Drought/BE-D3.mzXML"
> xset <- xcmsSet(cdffiles)  # peak picking (step 2)
Error in xcmsSet(cdffiles) : 
  Chromatographic peak detection failed for all files! The first error was: Error in object@backend$getPeakList(x): [SpectrumList_mzXML::HandlerPeaks] Invalid pair order.

I am not sure what is happening. I load the xcms library already but this happened still. Another person using R 3.3.0 did not encounter this issue while other people use R 3.5.0 experienced the same thing. Is this version issue? 

Here is the required output

From the error message I'd say there is a problem in reading your files. Some time ago we switched from mzML/mzXML data import using the Ramp backend to the proteowizard libraries (because they represent the standard implementation of the mzML format).

Could you please try the following:

library(mzR)
fh <- openMSfile(".//Control/BE-C1.mzXML", backend = "pwiz")
hdr <- mzR::header(fh)
nrow(hdr)
spctr <- mzR::peaks(fh)
length(spctr)
mzR::close(fh)

## Repeat with backend Ramp
fh <- openMSfile(".//Control/BE-C1.mzXML", backend = "Ramp")
hdr <- mzR::header(fh)
nrow(hdr)
spctr <- mzR::peaks(fh)
length(spctr)
mzR::close(fh)

And report the results?

Another suggestion: please use the newer xcms functions for data handling and analysis (instead of the xcmsSet function). Have a look at the xcms vignette for more information.

Hello,

Thanks for your help.

The error message showed up like this.

 

> library(mzR)
> fh <- openMSfile(".//Control/BE-C1.mzXML", backend = "pwiz")
Error in openMSfile(".//Control/BE-C1.mzXML", backend = "pwiz") : 
  File .//Control/BE-C1.mzXML not found.
> setwd("C:/Users/yuchiu/Google Drive/WVU/2018 Summer/PLSC593A Introduction to Metabolomics/test/test")
> fh <- openMSfile(".//Control/BE-C1.mzXML", backend = "pwiz")
> hdr <- mzR::header(fh)
> nrow(hdr)
[1] 5835
> spctr <- mzR::peaks(fh)
Error in object@backend$getPeakList(x) : 
  [SpectrumList_mzXML::HandlerPeaks] Invalid pair order.

I also see this warning message when I try to load library xcms

 mzR has been built against a different Rcpp version (0.12.16)
than is installed on your system (0.12.17). This might lead to errors
when loading mzR. If you encounter such issues, please send a report,
including the output of sessionInfo() to the Bioc support forum at 
https://support.bioconductor.org/. For details see also
https://github.com/sneumann/mzR/wiki/mzR-Rcpp-compiler-linker-issue.

1st, please re-install mzR using BiocInstaller::biocLite("mzR").

For the error, seems that proteowizard has problems reading this file. Can you please try the second part, i.e. with openMSfile and the backend = "Ramp" option?
