+**No options available? How to re-detect metadata**
+
+If you see a &quot;No options available&quot; within the &quot;**Select references (chromosomes and contigs) you would like to restrict bam to**&quot; drop down, you need to re-detect metadata for the dataset you are trying to process. To do this follow these steps:
+
+1. Click on the **pencil** icon adjacent to the dataset in the history
+2. A new menu will appear in the center pane of the interface
+3. Click **Datatype** tab
+4. Set **New Type** to **BAM**
+5. Click **Save**
+
+The medatada will be re-detected and you will be able to see the list of reference sequences in the &quot;**Select references (chromosomes and contigs) you would like to restrict bam to**&quot; drop-down.
