SPUTNIK: an R package for peak selection of Mass spectrometry imaging data

If you find SPUTNIK useful, please consider citing our work :)

Inglese, P., Correia, G., Takats, Z., Nicholson, J. K. & Glen, R. C. (2018). SPUTNIK: an R package for filtering of spatially related peaks in mass spectrometry imaging data. Bioinformatics (Oxford, England)

Description

SPUTNIK is an R package consisting of a series of tools to filter mass spectrometry imaging peaks characterized by a noisy or unlikely spatial distribution. SPUTNIK can produce mass spectrometry imaging datasets characterized by a smaller but more informative set of peaks, reduce the complexity of subsequent multi-variate analysis and increase the interpretability of the statistical results.

Export Function

Hi,
Is there an export function built in to the SPUTNIK package or does one have to code it themselves?
Thanks!

SSIM function - final formula

I'm wondering if implementation of SSIM function is correct, in file graph_funcs.R
265 ssim <- ( (2*mux*muy+C1) * (2*sigxy+C2) ) / ( (mux**2+muy**2+C1) * (sigx+sigy+C2) )
should there be
ssim <- ( (2*mux*muy+C1) * (2*sigxy+C2) ) / ( (mux**2+muy**2+C1) * (sigx**2+sigy**2+C2) ) Instead?

Formula (13) in http://www.cns.nyu.edu/pub/lcv/wang03-preprint.pdf

(Sorry, I accidently pressed ctrl+Enter instead of Enter and so the issue got posted before I finished the comment)
