When I load a state file I need to be able to have access to additional parameters that are in the new tecplot files. For instance, if I have three vector components (x, y, and z) I will want to add additional parameters later like temperature, volume fraction, etc. They are always added after to the end of the list. But the tecplot reader never recognizes that there are additional parameters when reading in the new tecplot data files.
Also, when selecting new tecplot data files there are likely a different number of new tecplot data files (e.g., old - 5, new - 10) because of refining the time period over which the visualization will be conducted or a longer transient. Should’t they just be added to the internal array when using multple tecplot data files?
Thanks,
John

I’ll try to get data from a smaller model, I exceed the 4MB filesize limit.

[No-TV.zip](https://discourse.paraview.org/uploads/short-url/aSyySePiEZgm3F5k9HVsp9cS9GR.zip) (482.1 KB)

No-TV has four parameters, Yes-TV adds a new parameter (TV).
I load the No-TV, save a PVSM, disconnect, load the PVSM and select the Yes-TV set and it will not recognize the new parameter.

Indeed, statefiles are not intended to be used as macros. You may want to use a macro instead.

Okay, but the implication in loading new data files is that additional data should be possible either more than the previous number of data files and/or more the the original number of parameters.
Anyway, not sure how to go about writing a macro to replace the data files one a statefile is built.
Thanks,
John

You lost me there. A (python) macro is intended to automatize your workflow. A statefile is a state of the application. You should not point it to a different file.
You can enable the python trace to generate a macro of your actions.

I understand the distinction, but when there is an option when opening a state file to select different data files the assumption is that there is new data.

It is intended for easier relocation of files, not for loading new files.
