# filtering trace tables by spot intensity

## copies localization files

Use a generic path (with `*`) to give a set of files:

```
localization_cp_files --files /user/DATA/exp_7/*/localizations.dat --destination_folder .
```

```{note}
You can check your generic path with:
`ls /user/DATA/exp_7/*/localizations.dat`
```

## merges localization files

```
ls *.dat | localization_merge
```

## filters repeated spots while keeping only the one with highest intensity

```
trace_filter --input merged_traces.ecsv --clean_spots --localization_file merged_localizations.ecsv
```
