# PdfGetXSaveAscii

`PdfGetXSaveAscii` exports the PDF signals returned by `PdfGetXProcessor` into a set of plain-text files—one file per signal type (`iq`, `sq`, `fq`, `gr`) and per averaged profile.

## Inputs

- `filename`: Base filename ending with `.h5`. The task derives the ASCII filenames from it.
- `results`: List of `PDFGetter` objects generated by `PdfGetXProcessor`.
- `info`: Metadata dictionary containing the averaging information (`nb_avg`).

## Outputs

- `saved`: Boolean set to `True` when at least one file is created.
- `filenames`: List of paths to the generated ASCII files.

## File naming and contents

- Files are saved alongside the base `filename`. The suffix encodes both the signal type and the averaging chunk, e.g. `results_nb_avg4.iq`.
- Each file contains two columns (axis and signal) with a header that records the PDFgetX configuration used to generate the data.
- Empty or missing signals are skipped gracefully with debug logging.

```python
from ewokspdf.tasks.save_ascii import PdfGetXSaveAscii

save = PdfGetXSaveAscii()
save(filename="/tmp/results.h5",
     results=processor.outputs.results,
     info=processor.outputs.info)

print(save.outputs.filenames)
```
