+## 代码逻辑介绍
+
+DNASequence处理
+
+DNA是双链的，互为互补链，对DNA样本进行测序时不能确认测出的是哪条链，所以就把所有DNA片段的互补链全算出来，和原文件放在一起组装。
+
+> 输入格式：只是演示样例，不保证其生物上的准确性，默认最大dna序列长度支持5e4，可自行修改代码扩容
+>
+> 程序将会从项目的根目录中打开filteredReads.txt并处理类似以下若干条dna序列

+>在编译完文件后会得到dna.pyd文件和python提示文件dna.pyi，用法如下
+```python
+import dna
+
+help(dna)
+
+dna.dna_reverse("filteredReads.txt","reversedSequence.txt")

+NAME
+    dna - DNASequence processing functions
+
+FUNCTIONS
+    dna_reverse(...) method of builtins.PyCapsule instance
+        dna_reverse(input_file_path: str, output_file_path: str) -> None
+
+        DNA is double-stranded and complementary to each other, and when sequencing a DNA sample you can't be sure which strand is being measured, so the complementary strands of all the DNA fragments are counted and assembled together with the original file.
