Error using SPM "using <a href="matl​ab:matlab.​internal.l​anguage.in​trospectiv​e.errorDoc​Callback..​."

Dear hivemind,

I am currently running analyses using SPM with Matlab. When executing the contrast manager I get the following error whcih I don't think had anything to do with SPM:

error using <a href="matlab:matlab.internal.language.introspective.errorDocCallback('cfg_util', 'cfg_util.m', 835)" style ="font-weight:bold">cfg_util</a> (<ahref="matlab: opentoline('cfg_util.m', 835,0)'>line 835<a>)

Can anyone help me with its meaning? There are no details on the error in the Matlab command line.

Best,

Paula
