 ## Abstract
-FScanpy is a Python package designed to predict Programmed Ribosomal Frameshifting (PRF) sites in DNA sequences. It integrates advanced machine learning models, including Gradient Boosting and BiLSTM-CNN, to provide accurate predictions. This tool is essential for understanding gene expression regulation in various organisms, including eukaryotes and viruses, and offers a robust solution for PRF prediction challenges.
+FScanpy is a Python package designed to predict Programmed Ribosomal Frameshifting (PRF) sites in DNA sequences. This package integrates machine learning models, sequence feature analysis, and visualization capabilities to help researchers rapidly locate potential PRF sites.
