mzDB output

[dominik-kopczynski]

Hi folks,

would it be possible to add a further output format for the thermo raw file parser, namely the mzDB file format [1]? With its index strategy and database structure, it is way faster to read them than parsing mzML files.

Cheers,
Dominik

it should be easy and is the original idea of the library, we have the parquet file export.

Hi @dominik-kopczynski, I think our good friend David have some plans on mzDB and ThermoRawFileParser.

It should be indeed possible to implement the whole conversion logic inside the ThermoRawFileParser library.
However I decided to test a different solution for the mzDB conversion implementation, which should allow me to reuse existing Java/Scala code. If we are happy about this experiment it should also help other folks working in C++, R and so, to use the ThermoRawFileParser library. It might be useful for data visualization on Linux for instance.

I have forked the current project and performed some changes enabling the embedding:

In parallel I have forked the Embeddinator-4000 project and created some Windows Docker files to simplify the build of the fork from sources:
https://github.com/david-bouyssie/e4k-dockers

I'm using Embeddinator-4000 to generate the glue code (a C-like library wrapping the C# one and a JAR file containing the wrapper).
Now I'm working on the integration in the mzdb4s project: https://github.com/mzdb/mzdb4s
I already have a prototype which is working on Windows. The next step is to make it work on Linux, but it should not be a bigger problem.

Feedback is welcome ;)

Here is a first pre-release including two converters (raw->mzDB and mzDB->MGF):

Note that the thermo2mzDB is a native executable which is targeting Linux Ubuntu. I could also deliver a Java program if needed.
