Dpi script error: "rake aborted, don't know how to build task"

[kgcoder25]

Hi, I am a researcher new to computational research and CAGE-seq analysis. I am trying to run this dpi script to compare it to our personal clustering process, but I keep getting the same error.

"rake aborted!
Don't know how to build task 'bw' (See the list of available tasks with rake --tasks)"

Rake also seems to abort for other tasks further down in the Rakefile. I am unsure what to do to fix this issue. Here is the code I am running on the console.

./identify_tss_peaks.sh -g ${directory}/hg38_star_2_7_9a/ -i 'ls ${directory}/*bed.gz | head -2' -o ${directory}/dpi1

Please help!
