I am using the Spyder3 IDE with Python 3.7.3 and have encountered, what to
me at least, is a rather strange problem.
The code, at this point is:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
"""
Created on Sat Apr 8 15:17:07 2017

"""
#import numpy as np
#import matplotlib.pyplot as plt
import pandas as pd
name = input("Enter Molecule ID: ")
print(name)
ligand_file = name+'_apo-1acl.RMSD'
print('Ligand file = ',ligand_file)
data = pd.read_table('ligand_file',skiprows = 7)
print(data)
The input file, in this example, 17-3_apo-1acl.RMSD is:

The output is:

I have used the ligand_file = line in other Python script that has worked
without any errors.
Google has not been a solution in his case. Pointers towards wolutions to
this problem will be much appreciated.
Thanks in advance.
