Failure opening ...\...sky - error on line X at column Y vogelw  2017-04-21 12:16
 
Hello,
Any thoughts on how I can recover from this error ?

Screen shot of ther error message attached: "The file contains an error on line X at column9

The XML section ending at that line is also attached.
      <precursor

....

      </precursor> # the line referred to in the error message

Nothing that I can see therein.

Cheers,
Walter

Can you press the "More Info" on that message box, and tell us what it says? (You should just be able to select the text of the stack trace and copy/paste it into your response).

In this case, I think you have discovered a bug in Skyline, and 44989 is the line that Skyline was on when the bug manifested itself.

I have never seen that error before.
Can you send us your entire .sky file?
If it is less than 50MB, you can attach it to this message.

I will also send you an email with alternative ways of sending us files.
 
Nick Shulman responded:  2017-04-21 13:45
Thank you for sending me your Skyline document.
It turns out that we have seen this error before:
https://skyline.ms/announcements/home/support/thread.view?entityId=f9de728b-016e-1034-b62a-da202582f7dc

This happens if your peptide contains sulfur (i.e. methionine) and you have too high of a resolution specified for the resolving power of the instrument on:
Settings > Transition Settings > Full Scan > MS1 filtering > Resolving Power

You can work around this issue and make it possible to open your Skyline document by opening the .sky file in a text editor.

On line 38, where it says:
precursor_res="400000"
change that to a lower number, such as "200000".

Sorry about this bug. I will try to fix this soon.

That worked.

Here is two skyline file, I don't know where the difference between them and why I can open one of them and why I can't open the other one...
RD120_testHeLa_190704Sched_3.sky : file that doesn't work
RD120_testHeLa190703nonSched.sky : this file is working



Thanks for your help

It appears that you somehow removed a heavy modification from your peptide settings while it was still in use.

If you open RD120_testHeLa_190704Sched_3.sky in a text editor and replace the line

        <heavy_modifications />

with these lines

        <heavy_modifications>
          <static_modification name="Label:18O(1) (C-term)" terminus="C" formula="O' - O" unimod_id="258" short_name="Ob1" />
        </heavy_modifications>

it should be OK again.

Thanks for using the Skyline support board!

Skyline, however, shouldn't be writing out a .sky file like this with an internal inconsistency that causes it to fail to load. If you can figure out the steps you took to get into the state where Skyline saved an inconsistent .sky file, we would be very interested in knowing those steps, so that we can fix Skyline to prevent that case.

I tried a few things myself, but haven't been able to cause this issue.

Thanks for reporting it.

Instead of modifiying every text file like you suggested Brian, I started over and I realize that, for no reason when I create a new skyline file, I have in peptides settings parameters 'Label:18O(1) (C-term)' that is added
settings >peptides settings >modifications >isotope modifications 'Label:18O(1) (C-term)'

So I had to remove it and this works!

I am investigating to find where does this come from and I will report it to you (if I find the issue)

Thanks a lot for your answers !
