R Documentation

Get Z-score threshold for an FWER corrected p-value

Description

https://github.com/spisakt/pTFCE

Usage

fwe.p2z(resel_count, FWEP = 0.05)

Arguments

`resel_count`	resel count
`FWEP`	FWER corrected p-value

Details

The p-value, corrected for multiple comparisons by controlling for family-wise error rate, is converted to a Z-score threshold. The parameter resel_count is the number of resels (resolution elements) in the image, and can be obtained e.g by smoothest() (see examples).

Value

Z-score threshold

Examples

## Not run: 
s=smoothest(zmap, mask)
fwe.p2z(resel_count=s$volume/s$resels, FWEP=0.05)

pTFCE=ptfe(zmap, mask)
fwe.p2z(pTFCE$number_of_resels, FWEP=0.05)

## End(Not run)
