# The Cancer Genome Atlas Ovarian Cancer for Ascites Segmentation (TCGA-OV-AS)
|
| 6 |
+
|
| 7 |
+
This dataset is derived from [TCGA-OV](https://wiki.cancerimagingarchive.net/pages/viewpage.action?pageId=7569497) Dataset. Download the data from TCIA with **Descriptive Directory Name** download option.

## Converting Images
|
| 10 |
+
|
| 11 |
+
Convert the DICOMs to NIFTI format using `dcm2niix` and `GNU parallel`.
|
| 12 |
+
|
| 13 |
+
1. Create the directory structure required for each NIFTI file:
|
| 14 |
+
1. `find TCGA-OV -type d -exec mkdir -p -- /tmp/{} \;`
|
| 15 |
+
2. `mv /tmp/TCGA-OV ./TCGA-OV-NIFTI`
|
| 16 |
+
|
| 17 |
+
2. Convert DICOMs to NIFTI
|
| 18 |
+
1. `parallel --jobs $n < jobs.txt` where `$n` is number of parallel jobs.
|

## Ascites Dataset
|
| 21 |
+
|
| 22 |
+
285 images that are free of corruption have been hand-picked for use. The images mostly consist of **ABDOMEN-PELVIS** scans (see: `metadata.csv` for full details).
