s1 variable missing in peerPC_cov.m

[RobertoDF]

Hi!

Thanks for making all the code available. I have a problem using peerPC_cov.m, where is the s1 variable from?
I tried the second output of svdecon but it doesn't work....

stringer-pachitariu-et-al-2018a/multiDactivity/peerPC_cov.m

Line 75 in 8dce0d5

cpc = corr(gather_try(s1(1,:)'), gather_try(Ff(ntrain,itest)' * u2(:,1)));

Looking around I found s1 defined in the SVCA function:

stringer-pachitariu-et-al-2018a/multiDactivity/SVCA.m

Lines 24 to 33 in 8dce0d5

	function [sneur, varneur, u, v, noise] = SVCA(Ff, npc, ntrain, ntest, itrain, itest)
	cov = Ff(ntrain,itrain) * Ff(ntest,itrain)';
	[u,~,v] = svdecon(cov);
	u = u(:,1:npc);
	v = v(:,1:npc);
	s1 = u' * Ff(ntrain,itest);
	s2 = v' * Ff(ntest,itest);
	sneur = sum(s1 .* s2, 2);
	varneur = sum(s1.^2 + s2.^2,2)/2;

If I add this definition of s1 to peerPC_cov.m the code seems to run fine but is everything correct?
