My question today is for experts using python programming to do Bioinformatic analyses. I am trying to run a well written script for creating scaffold from my blast sequences. I am however getting the error again and again. I have pasted the error I am getting
""""Traceback (most recent call last):
File "C:/Python27/DB/Attempt3.py", line 150, in <module>
File "C:/Python27/DB/Attempt3.py", line 143, in __main__
ContigsDict = myContigs (args.sequences)
File "C:/Python27/DB/Attempt3.py", line 49, in myContigs with open(file, "r") as f:
TypeError: coercing to Unicode: need string or buffer, NoneType found"""
Can somebody please advise me why I am getting his error.I know I have installed python and biopython as I am able to parse known sequences using this.
