Hi Jason,

Please post your questions to the mailing list (in CC).


Did you enable .gz support when you built the software Ray from source ?

Dear Admin,

Thank you for contributing this useful piece of software.

I am using Ubuntu as my working platform but i received an error "Rank 0 : no 
input files, aborting" when i executed Ray program of Ray-2.3.1.tar.bz2 which 
is downloaded from this website

https://sourceforge.net/projects/denovoassembler/files/
Ray, a de novo assembler using MPI 2.2 - Browse Files at 
...<https://sourceforge.net/projects/denovoassembler/files/>
sourceforge.net
Ray -- Parallel genome assemblies for parallel DNA sequencing


The command that i entered was

mpiexec -n 2 ray-build/Ray -detect-sequence-files SRR1633365 -show memory-usage

and the file SRR1633365.fastq.gz is in the folder SRR1633365

However, when i installed the Ray by using this command, it can be executed 
successfully.

sudo apt-get install Ray
mpiexec -n 2 Ray -detect-sequence-files SRR1633365 -show memory-usage


Could you please guide me the solution to this problem?

Thanks
Jason
