 - Intersect two files regarding the sequences' strand and save the result to the specified file:
 
-`bedtools intersect -a {{path/to/file_1}} -b {{path/to/file_2}} -s > {{path/to/output_file}}`
+`bedtools intersect -a {{path/to/file1}} -b {{path/to/file2}} -s > {{path/to/output_file}}`
 
-- Intersect two files with a left outer join, i.e. report each feature from {{file_1}} and NULL if no overlap with {{file_2}}:
+- Intersect two files with a left outer join, i.e. report each feature from `file1` and NULL if no overlap with `file2`:
