Description
Hi,sibeliaz is a super useful software ! But recently l can not use it smoothly, l just run : sibeliaz -k 15 -n *.fasta ,but the de_bruijn.bin was not processing.and l use top to see the process, it's not running. and then l found sibeliaz file . l follow the script, first l run twopaco and then l run sibeliaz_lcb,it works. so l wanna ask if that is right to split this process like that and why l can not use sibeliaz directly ? thanks a lot !
