Hi,

When using the `tavg` plugin, when I have the parameter `std-mode = summary`, where can I find the reports of the maximum and average standard deviation for each field? Sorry I might be missing the obvious here

It is in the `/stats` dataset inside each solution written out by the time averaging plugin. The `h5dump` utility can be used to extract it:

```auto
h5dump -d /stats -b --output=stats.ini tavg.pyfrs

```
