 samtools view allows to specify a reference sequence. This is required for SAM input with missing @SQ headers (which include sequence names, length, md5, etc) and useful (and sometimes necessary) for CRAM input and output. In the following the use of reference sequence in the CRAM format is detailed. 
-CRAM is (primarily) a reference-based compressed format, i.e. only differences between the stored sequences and the reference are stored. As a consequence the reference that was used to generate the alignemnts is always needed in order to interpret the alignments (a checksum stored in the CRAM file is used to verify that the only the correct sequence can be used), i.e. the CRAM file on its own is not useful per default. This allows for a more space efficient storage compared to BAM. But it is also possible to use CRAM without a reference with the disadvantage that the reference is stored explicitely (as in SAM and BAM).

-The Galaxy tool allows both possibilities using the "reference data" option:
+CRAM is (intended as a primarily) a reference-based compressed format, i.e. only differences between the stored sequences and the reference are stored. As a consequence the reference that was used to generate the alignemnts is always needed in order to interpret the alignments (a checksum stored in the CRAM file is used to verify that the only the correct sequence can be used), i.e. the CRAM file on its own is not useful per default. This allows for a more space efficient storage compared to BAM.

-- the default ("no reference") 
-- reference data can be chosen from history or built in genomes can be used
+The Galaxy tool **currently generates only CRAM without reference sequence**.
 
-The reference data required for reading/writing reference based CRAM.
+For reference based CRAM input the correct refernce sequence needs to be specified.
