# Job: ResLog Analysis

## **Description**

This feature generates plots that show how the resolution of a given structure increases as more particles are added to the reconstruction. This insight may be useful in determining whether a higher-resolution result is possible with more particles, or if fewer particles are needed to achieve the same resolution. The implementation in CryoSPARC is based on [Stagg, S.M., Noble, A.J., Spilman, M. & Chapman, M.S. ResLog plots as an empirical metric of the quality of cryo-EM reconstructions. Journal of Structural Biology 185 (3), 418-426 (2014).](https://www.sciencedirect.com/science/article/pii/S1047847713003377?via%3Dihub)

## **Input**

* Particles

## **Output**

* Particles

## **Common Parameters**

* `Reconstruction box-size`: The volume size to use for refinement. If this is *None*, use the full image size. Otherwise images are automatically downsampled
* `Symmetry`: Symmetry (e.g. C1, D7, etc.) of the dataset

## **Common Next Steps**

* Additional refinements with tuned number of input particles based on the ResLog analysis

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://guide.cryosparc.com/processing-data/all-job-types-in-cryosparc/post-processing/job-reslog-analysis.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
