+### Merging BWT files
+
+In the case you want to **merge BWT files** computing **DA**, you must provide DA and `file.docs` with the following option:
+
+*--da --docs*      
+  compute Document Array and output the number of documents into `file.docs` (required to use --bwt --da)
+
+**Example**
+
+```sh
+./eGap dataset/file1.fastq -o file1 --da --docs
+./eGap dataset/file2.fastq -o file2 --da --docs
+
+./eGap --bwt -o merge file1.bwt file2.bwt --da
+```
