In particular, comments in the input file header will not be preserved, some custom tags will be converted to strings, and original reference sequence order is not necessarily preserved.

-Note that currently comments in the input file header are not imported and some custom tags will be converted to strings, rather than preserving tag types. The caller must have WRITE permissions to the dataset.
+Notes on BAM import:  
+- Tags will be converted to strings - tag types are not preserved
+- Comments (@CO) in the input file header are not imported
+- Original order of reference headers is not preserved
+- Any reverse stranded unmapped reads will be reverse complemented, and their qualities (and "BQ" tag, if any) will be reversed
+- Unmapped reads will be stripped of positional information (referenceName and position)
