[Psidev-ms-dev] HDF5-based mass spectrometry formats

[jeleclai <jel...@un...>]

Hi all,

I am a Phd student in Stefan Tenzer's lab. We are currently working on a 
new format for mass spectrometric data, based on HDF5.

We started to develop this format because we struggled with ion mobility 
data: random access data to vendor's raw files is, as everyone knows, 
suboptimal, and especially in the case of including ion mobility, we 
foresee better ways to organize MS data in order to improve random access.

In this regard, the HDF5 library is of great advantage as it combines a 
simple and flexible way to structure the data with several efficient 
methods for I/O access.

Additionally, HDF5 library offers a good support for developers. It is 
already successfully implemented in many other scientific fields like 
Astronomy, Climatology, Genetics... All of this makes it a good 
candidate for future developing of standard formats of large data, which 
are interrogated in a random access way.

We would be very happy to bring this topic to discussion for the next 
PSI meeting!

Best wishes,

Jenny
