Prd

linc_convert.utils.io.prd

Load Kinetix .prd image stacks from local disk.

A .prd file is: [ header ][ frame 0 ][ gap ][ frame 1 ][ gap ] ... [ frame N-1 ][ padding ]

Each frame is width * height little-endian uint16 pixels stored row-major. There is a gap of padding bytes between frames but not after the last one.

The geometry parameters are read from a kinetixMetadata.txt file sitting next to the .prd file(s):

16      # data type, uint16
1000    # width
400     # height
8272    # header bytes
2661    # expected frames per full file
6912    # gap bytes (between frames, not after last frame)

PrdSetInterpreter 

PrdSetInterpreter(prd_set_path)

Assemble prd files into a single 3D volume with a Dask array.

read_kinetix_metadata staticmethod 

read_kinetix_metadata(path)

Parse a kinetixMetadata.txt file into its geometry parameters.

path may be the metadata file itself or a directory containing it.

get_prd_files staticmethod 

get_prd_files(path)

Return the .prd files for prd_set_path, in acquisition order.

assemble 

assemble()

Assemble all prd files into a single 3D volume with a lazy Dask array.

Returns:

Type Description
A Dask array of shape (frames_total, height, width), where
frames_total is the sum of the frame counts across all `.prd` files.
