Changelog Entry
To be copied to the draft changelog by merger:
vg convertoption--no-translationfor converting GBWTGraph to GFA directly without using the node-to-segment translation.Description
GBWTGraph can store a node-to-segment translation for conversions between GFA segments (string names, arbitrary length) and nodes (integer ids, often limited to 1024 bp). When GBWTGraph is converted to GFA, this translation is used to restore the original GFA. Sometimes this is undesirable and we really want a direct conversion to a GFA graph with the same nodes as the GBWTGraph. This is now possible by using
vg convertoption--no-translation.
