Hello Canu Team,

I am trying to run Canu v1.8 and got an error that it

failed to find the number of jobs in 'correction/0-mercounts/meryl-count.sh'.

Any help is much appreciated. Thank you.

Best Regards, Priyanka

What's in meryl-configure.err?

I'm guessing it will be complaining about failing to load some compiler library, which is usually caused by compiling on a machine that differs from the ones you're trying to run on (different OS version, or compiler not installed on the nodes, etc).

brianwalenz commented 5 years ago

Well, that wasn't very illuminating. :-(

That's the output from meryl-configure.sh. This has a series of 'meryl' commands that are attempting to decide how much data to process at one time. Can you run any of those commands by hand, on both the head node and a compute node? Best to leave out the file redirection, just to see any errors.

psur9757 commented 5 years ago

No errors I ran a couple commands and they all ran well. I removed threads parameter since I was running on the local node.

brianwalenz commented 5 years ago

Oh, sorry! I didn't notice this is PBS. There were some flaws with PBS support in the 1.8 release. Can you install the latest non-release version from github? It would be best to remove the current assembly directory before restarting - all it's done so far is copy the input reads to the assembly database.

If you can't (or don't want to) install the new version, this assembly should be small enough to run without grid support, using just one node. Canu options useGrid=0 maxThreads=24 maxMemory=96g will disable grid support, limit it to 24 CPUs and 96 GB memory. Allocating an entire node would be best, in which case you can omit the maxThreads and maxMemory options.

psur9757 commented 5 years ago

I updated Canu and restarted the process. This time the error is with submitting overlap jobs.

Assuming you're using the same command as before, remove your nodes/ppn settings from all the gridOptions. Canu will set these itself.

gridOptionsOBTOVL="-l walltime=156:00:00 -l nodes=1:ppn=8"

See the docs for option gridEngineResourceOption if you want to modify the format. The default for PBSpro is -l select=1:ncpus=THREADS:mem=MEMORY. What happened here is that both the older node/ppn format and newer select/ncpus options were set, and PBS doesn't like that.

Further, if all you're setting is walltime, you can use the global gridOptions= to set it for all components.

Last, once you've found a set of setting that works, you can put all these grid/system options into ~/.canu or $bin/canu.defaults (one per line) to set them for all future runs.

Thank you this issue is solved. My assembly ran to completion.

focusjava commented 5 years ago

How is your problem solved? I have this problem, too @psur9757

skoren commented 5 years ago

@focusjava are you using PBS? If so, there were issues with PBS support in the 1.8 release, using the 1.9 branch should fix them. If you're not on PBS then the error is likely due to a different cause and you should open a new issue describing it in detail and posting the same logs as above (e.g. meryl outputs).
