prostatectomy/TRANSFER_README.md

Prostatectomy split archive transfer guide

This is a new transfer guide. It does not replace or modify the source dataset's original prostatectomy/README.md.

Archive layout

All archives are uncompressed tar files. Every archive retains the top-level prostatectomy/ path, so extracting every part into the same parent directory reconstructs the original dataset tree.

First batch:

• prostatectomy_non_video.tar: original README.md, data/, and meta/
• prostatectomy_videos_chunk-000.tar
• prostatectomy_videos_chunk-001.tar
• prostatectomy_videos_chunk-002.tar
• prostatectomy_videos_chunk-003.tar
• prostatectomy_videos_chunk-004.tar

Remaining video chunks to package after the first batch has been uploaded and local space has been reclaimed:

• chunk-005 through chunk-010

Files ending in .partial are still being written and must not be uploaded. Only upload files whose names end exactly in .tar.

Reconstruct on the destination machine

Choose the parent directory that should contain prostatectomy/:

DEST_PARENT=/path/to/cmr_surgical
mkdir -p "${DEST_PARENT}"

tar -xf prostatectomy_non_video.tar -C "${DEST_PARENT}"
for archive in prostatectomy_videos_chunk-*.tar; do
    tar -xf "${archive}" -C "${DEST_PARENT}"
done

This produces:

${DEST_PARENT}/prostatectomy/
├── README.md
├── data/
├── meta/
└── videos/
    ├── chunk-000/
    ├── chunk-001/
    └── ...

Parts may be extracted in any order. Extracting later batches into the same DEST_PARENT adds the remaining chunks without changing existing chunks.

Basic verification

Check an archive before extracting:

tar -tf prostatectomy_non_video.tar >/dev/null
tar -tf prostatectomy_videos_chunk-000.tar >/dev/null

After every batch has been extracted, the complete dataset should contain video directories chunk-000 through chunk-010.
