Hi Chris,
The design of MSNoise is that you do the moving stack of 60 days
(=smoothing over the last 59 days) and compare that to a REF. This is
achieved with "mov stack"= "msnoise stack -m". If you want to make the
step stacking , i.e. only exporting the stack for each nth day, you need
to run the "msnoise stack -s" command, but it's really not well
documented and implemented, e.g. the dvv plots will probably fail.
The fact that the first 60 days are the same are a choice that goes back
to the orginal codes I implemented, assuming the stack should be the
same as long as the number of days of movstacks are not available. It's
a bad implementation and I really would like to change this in the future.
The "-i 9999" command is only useful if you want to re-stack data
computed more than 1 day ago.
Let me know how it goes

Hello,
I came across a stack error when using MSNoise and could not find the solution
