Error in the "autoNoise0" stage while doing de novo assembly of Bionano data

I am trying to do de novo assembly of Bionano data. Bionano Pipeline tools and Access server have been installed on a Virtual Machine running Ubuntu 18.04. When I run it with the Bionano data-set downloaded from Genome in a Bottle (all.bnx from, the pipeline runs fine. But with my dataset, it gives an error in the "autoNoise0" stage.

The Terminal output ends with the following:

Could someone kindly guide me what might be wrong in the run with my own datbase.

I came to the same problem, but cannot find any solution by google. May my experience help someone. It may be that your python subprocess.Popen cannot find the command on your system. Type print(jobArgs) before line 822 of the file: [path]/tools/pipeline/1.0/Pipeline/1.0/,
Just like this:

super(SingleJob, self).__init__(jobArgs, stdout=stdout, stderr=stderr)
self.startTime = time.time()
self.isRunning = True

Check the commands on you system and

yum install [the command for centos]
