Remove accession numbers form nexus tree files

Question

[AB]

Hi,

I'm relatively new to bioinformatics and am trying to work out how to remove the accession numbers from a Nexus formatted tree.

e.g.

#NEXUS
BEGIN TREES;
    TREE 1 = (CY116033b|A/swine/England/195852/1992,(((CY038004b|A/swine/En$
END;

I want to remove every accession number between the ( and | as this is causing issues with downstream programs.

I've tried sed (commands such as sed -e 's/.*\([A-Z][A-Z][0-9][0-9][0-9][0-9][0-9][0-9]\).*/\1/g' but can't seem to get it to work.

Does anyone know how to do this?

Any help would be much appreciated!
