running EOF analysis with z-score normalisation, (-zl,zl) limits on maps. need to change spectrals to non-log axis
adding logx=F does nothing for spectralfn.. try something else
can plot on linear axis by saving spectrum and 1/frequency as separate objects, plot those against each other
plots period. fix xlim and ylim! remove second figure? not sure what it adds...
changed xlim to length of freq range, ylim to max of both spectrum techniques
xlim changed to 0-max(frequency). second plot now shows freq, bottom shows period
changed zlims in comparefn to -zl,zl to work with z-score normalisation
working on globalising comparefn for any number of selected regions (tho not sute it's worth the effort)
