Error with 'python mtag.py -h'

[isobel16]

Hi there,

When I try to run mtag, and even try to check the options using python mtag.py -h, I get the following error:

Traceback (most recent call last):
File "/gpfs3/well/davies/users/smg484/MTAG/mtag/mtag.py", line 19, in

print 'IRWLS update:', new_w.shape, w.shape

SyntaxError: Missing parentheses in call to 'print'. Did you mean print('IRWLS update:', new_w.shape, w.shape)?

Any suggestions would be great, thank you.
