Describing the issue

MetaDraw crashed while attempting to open the Chimeric Scan View.

Reproducing the error

The scan being viewed was an ambiguous ID

• Protein database

n/a

• Mass spectrometry file types

.MZML

• Settings

defaults

• Example datafiles

Full sequence of peptide:
HGLDNY[Custom:NPA_Desthiobiotin on Y]RGYSLGNWVC[Common Fixed:Carbamidomethyl on C]AAKFESNFNTQATNR|HGLDNYRGY[Custom:NPA_Desthiobiotin on Y]SLGNWVC[Common Fixed:Carbamidomethyl on C]AAKFESNFNTQATNR

Path to folder with psm file and mzML file containing peptide:
"Z:\Users\Madeleine\CrashDataFiles"

Expected behavior for GUI

Expected to see the chimeric scan view

Additional context

[mzhastings]

also fragment ion brackets aren't shown when looking at the ambiguous IDs child scan view (except for the first option)

Thanks for this report! The crash is an issue that I will look into.

The lack of fragment ions annotations is intended. When we write the psm/peptide file only the matched fragment ions from the first ambiguous option is outputted. This means MetaDraw does not have enough information to accurately annotate any other ambiguous search result.
