After it is running, appear an awk syntax error: ...visualizing round 0 results: :) -p flag was triggered. Running with GNU Parallel support parameter set to false. :) -q flag was triggered, starting calculations for 1 threshold mapping quality :) -i flag was triggered, building mapq without :) -c flag was triggered, will remove temporary files after completion ...Remapping contact data from the original contig set to assembly ...Building track files awk: /data/hechun/software/3d-dna-master/lift/lift-input-annotations-to-asm-annotations.awk: line 108: regular expression compile failed (syntax error ^* or ^+) Please tell me how to resolve it.
