Subject: Function generating index text was assuming there'd always be an index
X-Git-Tag: v0.5.5~80
X-Git-Url: http://woldlab.caltech.edu/gitweb/?p=htsworkflow.git;a=commitdiff_plain;h=24da0614888d5b7f437b65823fbba793430ae00a

Function generating index text was assuming there'd always be an index
index_sequence was returning none for library adapter types that didnt
support indexing. this caused my tests to fail for older
libraries.
