If you don't need the power of regex, it's faster to use string methods:
filter0 = line.replace("<G_", "")
filter1 = filter0.replace(".", " ")
Actually, seeing as how you're reading all the lines in one go anyway,
it's probably faster to do this instead:
text = filetoread.read()
text = text.replace("<G_", "")
text = text.replace(".", " ")
# Write new log file
filetowrite.write(text)
