While meganizing a daa file with daa-meganizer, I get the following exception when performing weighted LCA:
Caught:
java.lang.NullPointerException

command is:
daa-meganizer -i .daa -v -a2t prot_acc2tax-May2017.abin -alg weighted
reference is NCBI nr
MEGAN Ultimate Edition (version 6.8.18, built 21 Jul 2017)
Any insight into why this happens? When I meganize directly in MEGAN, no reads are binned.
