It is not really a probelm to clean the gradients without volume
triggers. E.g. Bergen plugin
(http://fmri.uib.no/tools/manual_bergen_plugin.pdf) has an option to
detect the gradient onset form your raw EEG (ECG, EMG, whatever). It
doesn't matter how many channels you have, average arteifact subtraction
works channel by channel. The only thing you may take care of is that
your data contains only real gradient onsets and doesn't include short
RF onsets in the beginning of recording. And it is also good to know
your TR at least approximately.
Please, ask if you have more questions.
