[pdal] In two LAZ files "WARNING: files have different point types: 3 vs 7"

[Ulises Ibarra]

Hello again: It is my mistake.
I apologize with you, I have identified the origin of the problem, my
clumsiness:
I did something like this: lasview *1*.laz, thinking that it was going to
show me only two LAZ files out of many that a folder contains, but there is
a "1" in all the files, so it took one of them whose extension is "
copc.laz", and it is this file that has a difference in the values that I
previously showed you:

    "compressed": true,
    "copc": true,
    "copc_info":
    {
      "center_x": 580870.5205,
      "center_y": 3596336.288,
      "center_z": 3908.8785,
      "gpstime_maximum": 1.691216388e-306,
      "gpstime_minimum": 392153449.3,
      "halfsize": 2701.4855,
      "root_hier_offset": 1795993,
      "root_hier_size": 128,
      "spacing": 42.21071094
    },
    "count": 130872,
    "creation_doy": 1,
    "creation_year": 1,
    "dataformat_id": 7,
    "dataoffset": 1342,
    "filesource_id": 0,
    "global_encoding": 16,
    "global_encoding_base64": "EAA=",
    "header_size": 375,
    "major_version": 1,
    "maxx": 583572.006,
    "maxy": 3596810.044,
    "maxz": 1317.599,
    "minor_version": 4,
    "minx": 578169.035,
    "miny": 3593634.802,
    "minz": 1207.393,
    "offset_x": 580870.52,
    "offset_y": 3595222.423,
    "offset_z": 1262.495,
    "point_length": 36,
    "project_id": "00000000-0000-0000-0000-000000000000",
    "scale_x": 0.001,
    "scale_y": 0.001,
    "scale_z": 0.001,
    "software_id": "",

There is the:      "dataformat_id": 7,  and "     "point_length": 36, "

Sorry and Thank you
