Add Descriptions to Glycan Structures
add_struct_descriptions.RdThis function adds columns about glycan structural properties
to the variable information tibble.
Depending on the glycan type (N-glycan, O-glycan),
different columns are added.
Current, only N-glycan descriptions are implemented.
See glymotif::describe_n_glycans() for columns added.
Arguments
- exp
An
experiment()object.
Details
The function relies on the glycan_structure column in
the var_info tibble, and it should be a glyrepr_structure object.
If you use the glyread package to directly read results from search engines
(such as pGlyco3), this column will be automatically added to var_info.
If you construct the glyexp_experiment object yourself, you need to ensure
that this column exists and its type is glyrepr_structure.
See glyrepr::glycan_structure() or glyrepr::as_glycan_structure()
for how to create such objects manually.
