What's the 'dbscan' in mpi_args?

[shanpinliu]

Hello!
I got interested to reproduce the workflows, but it stop at the subprocess in functions of clusterZ() and runSubProcess().
The mpi_args, [ "dbscan", "-i", "-b", "-m", "-e", "-o" ], are unrecognizable on my PC, see outputs:

**>>>/usr/bin/dbscan-bin: invalid option -- 'i'

dbscan - scan a db file and dump the contents common options: -f specify db file, -R dump as raw data, ...**

I guess the 'dbscan' is a density-based-spatial-clustering module, but I cannot find any pipe importing it. My computer took it as a database scanning tool. Then, the other mpi_args were unmatched with the scanning tool, and dbscan aborted unexpectedly.
So, what's the 'dbscan', how to fix it?

Thanks in advance,
Best,
Shanpin

Hi,

Have look at the following:
https://github.com/Geodels/plateInputs

You will need to install:

1. PnetCDF
2. and then Parallel dbscan

Hi Tristan,

Thanks for your response.

It took a few days to build the OpenMPI, PnetCDF, Boost and PnetCDF. Conflicts between the apps are the biggest challenge.
I can run the Parallel-DBSCAN now!
