 # Scoring
 
-The `output.gtf` generated by TERRACE consists of abundance values in the `score` field of the GTF file by default. We provide a Random Forest pre-trained model to generate more reliable scores (between 0 to 1) and integrate them in the `score` field of the GTF file. After integrating the scores, a user-defined threshold can be provided to generate a supplementary precise.gtf file that contains circRNAs with scores above the given threshold. Please refer refer to [RF-scoring/README](https://github.com/Shao-Group/TERRACE/blob/master/RF-scoring/README.md) for details of score generation, integration, and precise.gtf file.

 To make use of the scoring functionalities, TERRACE need to be run to generate a feature file as follows.
