errors in ft_componentsanalysis

Dear Fieldtrippers,

 I have a little problems with cft_componentanalysis and the 'runica' option


When running  Fieldtrip20100822 on matlab2008b (on Linux and running filedtripdefs before starting the calculations) I get a complaint about the notorious missing randperm.m
??? Undefined function or method 'randperm' for input arguments of type 'double'.

Error in ==> runica at 1063
 timeperm=randperm(datalength); % shuffle data order at each step

Error in ==> ft_componentanalysis at 252
 [weights, sphere] = runica(dat, optarg{:});

I thought that running filedtripdefs would take care of this, but seemingly it doesn't.

On the other hand if I run it on matlab 2007a, then ft-componentanalysis/runica stops with a warning that the "try catch" syntax will not be supported in future matlab versions ?
I do not get an actual error because whatever happens happens in a try-catch statement so errors are suppressed


Any suggestions welcome,
Michael
