IR removal: NegPy vs OpenICE

[erioho]

Hello, Just using NegPy to process tons of negatives. BUt I found as the figure, when using NegPy there will be a vertical straight strip, everytime at the same position just like a mask on it, when change it to OpenICE there is not such problem.

In my case I only found NegPy can help me to remove dust while Open cannot. Please advice.
