XCMS / Re: XCMS mzML support
Hi Steffen,

thanks, I got it to work.

The parser works fine but it takes a very long time (more than 10 min) to read in a simple 20 MB mzML file. Is there any particular reason for that?

Regards,

XCMS / Re: XCMS mzML support
Hi,

I'm on a LinuxMint 11 system (64 bit), which probably leaves space for a lot of things that could potentially be wrong.

BiocLite's version of XCMS works fine and so does your patched version.

Problems only start to occur when I try to get mzML support to work by out-commenting the corresponding entries in 'Makevars'.

"unable to load shared object '/home/beisken/R/x86_64-pc-linux-gnu-library/2.12/xcms/libs/xcms.so':
  /home/beisken/R/x86_64-pc-linux-gnu-library/2.12/xcms/libs/xcms.so: undefined symbol: _ZNK4pwiz6msdata11RAMPAdapter9scanCountEv"

I'll look into the problem.

Regards,
Stephan

XCMS / Re: XCMS mzML support
Hi Steffen,

many thanks for your reply.

I have successfully installed mzR and its dependency Rcpp. I had to re-archive mzR though.

For the patched XCMS version I outcommented XMLWriter.o in 'Makevars' because my compiler didn't like its library calls, i.e., it couldn't find the 'endian.hpp'.

It compiles fine but terminates while trying to test-load the program complaining about an undefined symbol in xcms.so. Guess there are some version incompatibilities?!

Have you come across that yet?

Best,
Stephan

XCMS / XCMS mzML support
Hi,

following the instructions on the wiki page (http://http://metlinwiki.scripps.edu/mediawiki/index.php/EnableMzMLSupport), I tried to enable mzML support in XCMS.

However, if I run 'R CMD INSTALL' on the xcms_1.26.1.tar.gz (contains pulled in and modified files), the compilation fails because it cannot find 'boost/integer/endian.hpp'.

Apparently R uses the external C++ libraries rather than the ones in the archive.

Does anyone happen to know how I can use the pulled in libraries?

Regards,
Stephan
