typeerror in plot dvv

[sujan1746]

I've used MSNoise so well but found a problem.

I run MSNoise in different frequencies and their mov_stack is same as "1,7,14,31" and it works very well in different frequencies.

However, in 0.3-0.6Hz, 6-10Hz, and 50-70Hz frequency (bandpass filter), there is a type error as below.

Processing works well until msnoise compute_dtt and it finished well but only for processing msnoise plot dvv.
msnoise plot dvv -m1, 7, 14 shows dvv plot well in 6-10Hz, msnoise plot dvv -m1, 7 works in 0.3-0.6Hz, and msnoise plot dvv -m1 works in 50-70Hz.

I saw config.csv and settings but could not find weird points..

If you have any idea for this problem, could you please let me know?
