+## 模型介绍
+Iterative_masking是在多个序列比对上训练的蛋白质语言模型，使用MSA Transformer迭代屏蔽相同的MSA来生成合成蛋白质序列。
 
-Supporting repository for: "Generative power of a protein language model trained on multiple sequence alignments" . We use MSA Transformer to generate synthetic protein sequences by masking iteratively the same MSA.
