Hello,
From looking at your screenshots, I think there may be an issue in the Spectronaut input data. You can see the intensity range says 0-0 and the intensity column is "PrecursorMz", when it should show "Intensity". Can you double check that your data matches the following example in MSstats?
```
spectronaut_raw = system.file("tinytest/raw_data/Spectronaut/spectronaut_input.csv",
package = "MSstatsConvert")
head(spectronaut_raw)
```
