Sure, here's some sample code for selecting a subset of point cloud data in Python using the open-source library PyntCloud:
```python
import numpy as np
from pyntcloud import PyntCloud
# Load point cloud data from file
cloud = PyntCloud.from_file("point_cloud.ply")
# Define a subset of indices to select
subset_indices = np.random.choice(len(cloud.points), size=5000, replace=False)
# Select the subset of points based on the indices
subset_cloud = cloud.points[subset_indices]
# Save the subset of points to a new file
PyntCloud(subset_cloud).to_file("subset_point_cloud.ply")
```
This code randomly selects 5000 points from the input point cloud data and saves them to a new file for further processing. Feel free to modify the code to suit your specific needs!
