        *   `radiobee aligner` is a sibling of `bumblebee aligner`. To know more about these aligners, please join qq group `316287378`.
        *   Uploaded files should be in pure text format (txt, md, csv etc). `docx`, `pdf`, `srt`, `html` etc may be supported later on.
        *   Click "Clear" first for subsequent submits when uploading files.
        *   `tf_type` `idf_type` `dl_type` `norm`: Normally there is no need to touch these unless you know what you are doing.
        *   Suggested `esp` and `min_samples` values -- `esp` (minimum epsilon): 8-12, `min_samples`: 4-8.
           -   Smaller larger `esp` or `min_samples` will result in more aligned pairs but also more **false positives** (pairs
           falsely identified as candidates). On the other hand,
           larger smaller `esp` or `min_samples` values tend to miss
           'good' pairs.
        *   If you need to have a better look at the image, you can right-click on the image and select copy-image-address and open a new tab in the browser with the copied image address.
        *   `Flag`: Should something go wrong, you can click Flag to save the output and inform the developer.
