Package: glyrex 0.1.0

Start with glymotif: find a familiar motif | A motif alone does not tell the whole story | From a motif to a search pattern | Meet your first collection of glycans | Start with one residue | Connect two residues | Add a linkage when it matters | Ask whether a residue is terminal | Describe a branch | Require a branch to be absent | Allow a choice of residues | Count and retrieve what you found | Put it together: sialylated LacNAc without a local Fuc branch | A few practical points | When you need a little more | Repeated units | Save a pattern for reuse

What is a pattern? | Keep structure notation and pattern notation separate | One residue, several choices, or any residue | Build a connected path | Specify a linkage only as precisely as you need | Restrict where the match occurs | Describe branches on a shared residue | Require a branch to be absent | Three different meanings of “not” | Optional residues and repeated units | Prefer longer or shorter repeats | Check neighbours without including them (advanced) | Give part of a match a name (advanced) | Build and check your own pattern | Interpret the results in structural terms
