Unknown error when opening LC-IMS-MS chromatograms rozas  2021-01-28 03:38
 

Hello SkyLine Team,

I would like to ask you about a problem that I have using the software ( Skyline version 20.2). The data that I want to treat was was generated with a Synapt G2-Si.

I can open the MS files when IMS was turn off but it is not possible to open the data when Ion mobility was working. The following error appears:

At 12:17 PM:
Failed importing results file 'G:\My Drive\30-REC-20-ERGO.PRO\Data\20201204-004.raw'.
[pwiz::CLI::msdata::SpectrumList::spectrum] Unhandled exception: Unknown Generic Error

if I click in more info:

I would appreciate if you can help me.

Thank you,

have a nice day.

Hi Laura,

If you can share your Skyline document (use the Skyline meny item File > Share > Complete), along with the raw file, I can have a look at this.

You can upload them to http://skyline.ms/files.url or we can arrange something more private.

Thanks for using the Skyline support board,

Hello,
I have tried to attach here one of the file that I can not open but it is too large.
I can not share you the file through Skyline because it is not opened in the software, so I do not have the option to share.
Please, If you know other way to send you the file, tell me.
sorry for the inconveniences,
Thanks a lot!
Regards

Skyline's File > Share > Complete menu item will zip up your Skyline document and any supporting libraries etc into a .sky.zip file. The raw file is a separate matter.

You can upload both files to http://skyline.ms/files.url or we can arrange something more private.

thank you.

Thanks for the files. There is something strange happening here, certainly - I can't even open that .raw file in SeeMS or msconvert.

I am wondering if it is damaged - are you able to open it in any other software, and view each scan? (Just opening it isn't a good test, you have to visit each scan the way Skyline or msconvert do.)

Best,

Brian

Hi Laura,

You're not the first user to run into this but I've just put a fix in today so it should work in the next daily release.

Hi Laura,

Until the next Skyline Daily drops you can work around this by converting to mzML with a new copy of msconvert, which should have Matt's fix in it now.

Thanks for taking the time to let us know about the problem.

Best,

Brian Pratt

Hello,

Thank you for your nice help and collaboration,

I could open my files by using msconvert and now I can open them directly with the new beta version.

kind regards,

Laura
