Resolution of complex repeats with long error-prone reads

Hi @AntonBankevich :
This is a much awaited enhancement. Thank you for this. We have used Flye to assemble four genomes. I was wondering if mosaicFlye can work on the existing assembly or not.
Cheers
Hardip
Dear Anton,
I am trying to use your tool to solve some repeatitive regions on my data, however there is something wrong with the option -t. As yo can see I have requested and use -t 48, however the program is just using 1 core.
$ nqstat_anu 10868520
%CPU WallTime Time Lim RSS mem memlim cpus
10868520 R ew6230 xc17 mosaic_N 2 00:14:47 48:00:00 24.6GB 24.6GB 1500GB 48
and the option --threads not recognized.
Could you may help me to understating what is happen?
Thank you,
Emiliana.
Dear Anton,
Hope you are well. I am trying the current mosaic code to solve a pretty complex region that Flye alone has not been able to solve correctly. However I can see a few errors when testing it with the toyset. BTW, I am running on a 24 core, 256GB RAM server with Centos 7.0.

Do you have any other recommended way of testing the current version. If you could give me some advice on how best to test it, I would be grateful.
Kind regards,
