Hi Admin,

I followed the INSTALL.txt guideline as attached to install Ray but i have no clue to go further.
Could you please guide me how to enable .gz support?

Thanks
Jason

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
Ray, a de novo assembler using MPI 2.2 - Browse Files at ...
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
