If this is the first time you use this toolbox, please go over the tutorial explaining you some key components about the analysis. The toolbox is a great way to improve the power and consequently reproducibility of your research. However, please read the information about responsible research practices to make sure you are doing it right.
Overview of the different steps
Before using this toolbox for power calculations, you need a pilot dataset. There are some important rules about what you can and cannot do with these data. Read the instructions carefully to make sure you don't harm the false positive rate of your study.
1. Specify the data
In the tab input you'll need to specify some parameters about the data and the experiment conducted. You can either upload data or link to an existing dataset.
2. Look at the data
In the tab viewer you'll be able to see your dataset (if you have linked to your data). This allows you to confirm that we've obtained the right data.
3. Extract Peaks
Our power calculations are based on the local maxima in the data. When you go to the peak table tab, the toolbox will extract the local maxima of your map and show you a table. Please allow a minute or two for this step to complete.
4. Compute Model
The key step of this toolbox is the estimation of the alternative distribution. In the tab model fit, you can visually inspect the fit of the model.
5. Power Analysis
In the tab power analysis you can see the power curves for your data, and you can specify your sample size and desired power. In the tab power table you'll then find a table with sample sizes and power.
