 ## About the data
 
 *	For this tutorial, we used a sample RNA-seq file from liver cancer from public study SRA http://www.ncbi.nlm.nih.gov/bioproject/PRJNA279878 or GEO http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE65485 (also available at EBI SRA here: http://www.ebi.ac.uk/ena/data/view/SRR1946637).

 - This pipeline can be extended to detect and quantify other microbes in RNA-seq as long as the sequence is known and available as a FASTA file.
   - Download the FASTA files of interest from NCBI , and concaterate them to create the reference FASTA file for this pipeline.
   - Build the reference index file
-  - Create the annotation file 
+  - Create the annotation file (similar to the example CSV file provided in this tutorial)
+  - The pipeline has been used to detect bacteria from RNA-seq data and has worked well.
 - Although not tested, this pipeline could be extended to detect and quantify microbes in DNA-seq.  
   - Can use BWA or Bowtie2 for alignment of DNA-seq data. And remember to output the unmapped sequences into a separate file.
   - The quantification step can only be done at the genome level, NOT at the transcriptome level.
-  - The variant calling step will work.
