[Bioc-devel] mzR: pwiz is now the default backend

[Rainer Johannes]

actually, I got quite some segfaults lately with the Ramp backend (was default up to now). With the pwiz backend I don't get them anymore.
Also, in xcms we were manually setting the backend to pwiz and did not experience any problems.

cheers, jo

Are there going to be any noticeable changes for the package users?  Does
it break compatibility?  Do I need to install something extra (like
ProteoWizard)?

In theory, we don't expect any downstream effects: no breaks, no extra
dependencies, ... developers and users shouldn't notice the change at
all. The pwiz backend has been available for many years, but was just
not the default.

Let's see what the practice says...

Dear developer,

For those who use mzR to access raw mass spectrometry data, please note
that we have change the default backend from Ramp to pwiz.

The old backend is still available using

 openMSfile(filename, backend = "Ramp")

See https://github.com/sneumann/mzR/issues/84 for details. Please do
raise any concerns or problems in that issue.

Best wishes,

Laurent
