Hi Adam,
sorry, I just solved the problem with Linux machine... I had an old alias
calling the Docker installation... sorry for the confusion.

Regarding windows, here is the pipeline JSON, I just copied it from the
tutorial...

{
"pipeline":[
"F:/2019_didalos/pdal/test_data/D_Geologie_Rundschuhhof_SolarTirol.las",
{
"type":"filters.pclblock",
"filename":"passthrough.json"
},
"foo.las"
]
}

All is saved in the passthrough.json file.

Silvia
