 This tool reads a list of transcripts and modifies each feature by:
 
-- shrinking it to the $ n $ first nucleotides or the *n* last nucleotides, or
+- shrinking it to the *n* first nucleotides or the *n* last nucleotides, or
 
-- extending it to $ n $ nucleotides towards the 5' direction (upstream) or the 3' direction (downstream).
+- extending it to *n* nucleotides towards the 5' direction (upstream) or the 3' direction (downstream).
 
 Note that the 5' or 3' direction depends on the orientation of the feature (the 5' end of a transcript located on the minus strand is on the right hand of this transcript!).
