Hi, everybody. Now I am trying to de novo assembly by SOAP.

My excuted code is this.

~/Downloads/SOAPdenovo2-bin-LINUX-generic-r240/SOAPdenovo-63mer all -s SOAPdenovo.config -o K47 -K -R 1>/home/Assembly/Cyanea-nozakii/all.log 2>/home/Assembly/Cyanea-nozakii/all.err

After it finish, occur Segmentation fault (core dumped)

Some people say the reason is max_rd_lenth, but I think my max_rd_length is ok. I checked by FastQC, sequence length is 301.

Here is my config file text.

#maximal read length
#average insert size(400~800 illumina)
#if sequence needs to be reversed
#in which part(s) the reads are used
#use only first 100 bps of each read
#in which order the reads are used while scaffolding
# cutoff of pair number for a reliable connection (at least 3 for short insert size)
#minimum aligned length to contigs for a reliable read location (at least 32 for short insert size)
#a pair of fastq file, read 1 file should always be followed by read 2 file

Please let me konw what's the problem of my job.;(((

Segmentation faults typically relate to memory / RAM, and may occur for diverse reasons. Developers ought to catch these errors better, and output more intelligent error messages. You said that it "works", though (?); do you mean that it runs to completion and then produces an error while outputting results?

Yes it was. I edited!

It is likely an issue related to memory / RAM. How much do you have available? Also, take a look at the comment here:
