[pdal] pdal pipeline | error 'No error'

[Rose Phillips]

Hi everybody,

Apologies if this is a banal question. I ran this pdal pipeline command, and got this error *PDAL: Unable to open stream for 'E:/test_density/*.las' with error 'No error'* :-

pdal pipeline C:/a/density_test_sub.json --readers.las.filename=E:/test_density/*.las --writers.gdal.filename=E:/test_density/test_density.tif
density_test_sub.json
{
    "pipeline" : [
    {
        "type" : "readers.las",
        "filename" : "input.las"
    },
    {
        "type":"filters.returns",
        "groups":"first, only"
    },
    {
        "type": "filters.merge"
    },
    {
        "type" : "writers.gdal",
        "resolution": 1,
        "nodata" : -9999,
        "filename": "pulse_density.tif"
    }
    ]
  }

Could this be because I used a wildcard for the readers.las.filename?
I'm attempting to create a raster representing all the files in a directory of las files.

(Thank you everyone at Hobu for pdal, it is an awesome piece of software!)

Many thanks and kindest regards
