when i execute this command line : eupan assemble soapdenovo -t 4 -k 23 -g data/ assembly_soap/ /home/hp/Bureau/SOAPdenovo2-src-r240

after runing it gives me this:

Process sample data/sampleA/ ...
Use of uninitialized value $seq in split at /home/hp/Bureau/EUPAN-v0.44/lib/EUPANassem.pm line 231.
Process sample data/sampleC/ ...
Use of uninitialized value $seq in split at /home/hp/Bureau/EUPAN-v0.44/lib/EUPANassem.pm line 231.
Process sample data/sampleB/ ...

I imagine SOAPdenovo either crashed or just didn't produce a scaffold file. Can you make sure all the files in your output directory (assembly_soap) are not empty? What does tree -s assembly_soap look like?

in the assembly_soap i have 3 sub-directories, in each one i have 5 files, the K23.cgContig and K23.cgScaffold files are empty.

after runing tree -s assembly_soap, i get this:

root@hp-HP-ProBook-640-G1:~# tree -s assembly_soap

assembly_soap [error opening dir]

0 directories, 0 files

the empty files are a possible culprit. is there anything special about K23?

is there any reason why SOAP would fail to assemble that particular sample? are the files bigger, or corrupt? if you remove that sample altogether does EUPAN finish its pipeline?

SOAP fails to assemble all the samples this is the problem.

oh so K23 is kmer size 23? try running SOAPdenovo separately from EUPAN and post whatever errors you see as a new Biostar question
