Hi again,
Changing the image size has corrected the alignment problem!
But when I increased the length of the rows, simply by copying and pasting the original sequences, it has got one of those minor errors preventing it running again (when it says a row/the style file refers to something wrong).
I have checked the whole thing this time and can't spot any typos!
I attach the current excel file and style file.
Do you have any suggestions as to what could be wrong this time?
