+
+**Example**
+
+Concatenating Dataset::
+
+    chrX  151087187  151087355  A  0  -
+    chrX  151572400  151572481  B  0  +
+
+with Dataset1::
+
+    chr1  151242630  151242955  X  0  +
+    chr1  151271715  151271999  Y  0  +
+    chr1  151278832  151279227  Z  0  -
+    
+and with Dataset2::
+
+    chr2  100000030  200000955  P  0  +
+    chr2  100000015  200000999  Q  0  +
+
+will result in the following::
+
+    chrX  151087187  151087355  A  0  -
+    chrX  151572400  151572481  B  0  +
