-## Data Preprocessing
-Check ```scripts/pp_DATASETNAME.py``` for the way to pre-process the original datasets. This will create the necessary files for you, e.g. ``rectify_map.h5``, ``calib_undist.json`` and ``t_offset_us.txt``.

-Please note, the training data have the size of about 1.1TB (rbg: 300GB, evs: 370GB).

 First, download all RGB images and depth maps of [TartanAir](https://theairlab.org/tartanair-dataset/) from the left camera (~500GB) to `<TARTANPATH>`
 ```bash
 python thirdparty/tartanair_tools/download_training.py --output-dir <TARTANPATH> --rgb --depth --only-left

+`dirsfile` expects a .txt file containing line-separated paths to dirs with .png images (to generate events for these images).
 
-We provide scene infomation (including frame graph for co-visability used by clip sampling). (Building dataset is expensive).

+#### Data Preprocessing
+We evaluate DEVO on seven real-world event-based datasets ([FPV](https://fpv.ifi.uzh.ch/), [VECtor](https://star-datasets.github.io/vector/), [HKU](https://github.com/arclab-hku/Event_based_VO-VIO-SLAM?tab=readme-ov-file#data-sequence), [EDS](https://rpg.ifi.uzh.ch/eds.html), [RPG](https://rpg.ifi.uzh.ch/ECCV18_stereo_davis.html), [MVSEC](https://daniilidis-group.github.io/mvsec/), [TUM-VIE](https://cvg.cit.tum.de/data/datasets/visual-inertial-event-dataset)). We provide scripts for data preprocessing (undist, ...).
+
+Check `scripts/pp_DATASETNAME.py` for the way to preprocess the original datasets. This will create the necessary files for you, e.g. `rectify_map.h5`, `calib_undist.json` and `t_offset_us.txt`.
