Can't run CDHIT from outside the directory

[sidhomj]

When I try to call CD-HIT from two directories above the folder which contains the source code, I get an error as follows: The code works when called from within the directory but has issues from anywhere else. Help?

================================================================ Program: CD-HIT, V4.7 (+OpenMP), Nov 02 2017, 09:50:28 Command: cdhit-master/cdhit-master/cd-hit -i PP_3_D-3_02.fasta -o out -c 0.8 -n 3

Started: Thu Nov 2 10:59:49 2017

                        Output
