What is the language of this mass spectrophotometry data processing output file

Question

[serpalma.v]

Dear community, I have been assigned a task to retrieve information from files that were processed from raw mass spectrophotometry data (file.mzML). These files have just ".data" as extension and when I open them, I cannot recognize the language and therefore I cannot load them into R and work on them.

The files with the .data extension are contained in this folder:

ftp://ftp.pride.ebi.ac.uk/pride/data/archive/2015/11/PXD000299/

Could someone take a look at any of the files and tell me the language is in (e.g. F010439)?

Thank you very much!

Take a look at http://www.ms-utils.org/wiki/pmwiki.php/Main/SoftwareList for tools that work with Mass Spec data.
File formats for Mascot tools are described here.
