|Error when inserting cross-linked peptides into document||Juan C. Rojas E.||2022-06-09|
Hi Skyline team,
So I am trying to insert a set of cross-linked peptides into Skyline through Edit -> Insert -> Peptides... by copying a list of crosslinked peptides that I parsed from a MeroX output into Skyline format. I loaded a .txt file (attached) with these sequences in Excel and attempted to copy-paste the whole list into the window in Skyline as I usually do for other "normal" peptides, but keep getting a "This peptide sequence contains invalid characters".
Strangely, when I click inside the cell of "Peptide Sequence" and paste a single sequence from the parsed list it accepts the entry. Any ideas what is going on?
Attached is also the Skyline document with the required mods and some pre-loaded peptides.
Hope ASMS was fun!
