| # 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/`: |
|
|
| ```bash |
| 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: |
|
|
| ```text |
| ${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: |
|
|
| ```bash |
| 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`. |
