Estimated time for DADA2 process

sorry for late updating my status.
actually one process with maxee 2 and truncn-q 2 options was finished yesterday (it took total 16 days, the other process with maxee 2 and trunc-q 0 is still running at day 18 now.), and I wanted to check the output files today. Two output files look ok with 5.8M table.qza and 17.4M rep-seqs.qza. but the log file showed some error message in the final step (I will attach the log file B2840_mx2_tq2.txt (8.8 KB)
.)
now I'm trying to convert them to visualization files. But the converting table.qza to table.qzv showed an error message with "core dumped", and I found the solution here (Error in qiime feature-table summarize - #2 by thermokarst), so it's running well. but it seems to take long again (so far 40min passed).
