+-b, --bootstrap-samples=INT   Number of bootstrap samples (default: 0)
+    --seed=INT                Seed for the bootstrap sampling (default: 42)
+    --plaintext               Output plaintext instead of HDF5

+    --rf-stranded             Strand specific reads, first read reverse
+-l, --fragment-length=DOUBLE  Estimated average fragment length
+-s, --sd=DOUBLE               Estimated standard deviation of fragment length
+                              (default: -l, -s values are estimated from paired

+                              prevent zero valued priors. Supplied in the same order
+                              as the transcripts in the transcriptome
+-t, --threads=INT             Number of threads to use (default: 1)
+    --verbose                 Print out progress information every 1M proccessed reads
