I installed bowtie2 following the instructions given on

http://bowtie-bio.sourceforge.net/bowtie2/manual.shtml#getting-started-with-bowtie-2-lambda-phage-example

When running the example though, I get the following error

The error is basically:

Error: could not open /root/bowtie2-2.2.2.3/example/reference/lambda_virus.fa

Which means it cannot find the file:   /root/bowtie2-2.2.2.3/example/reference/lambda_virus.fa

You should check if you have that file in the path stated.
