Dear xhosts, seeds & resoluters, particulary MGH-experts:
Finally, I got the optseq run on my SuSE6.3-LINUX. However, I
encountered a couple of important details to ask for:
1. For a simple efMRI-design specification, Matlab has properply started
up printing out the "seed", "Eff" and "trmin". I can figure out the
latter 2 but what is the "seed"? And what does the "Eff" [ectiveness]
number tell me precisely, i.e. in a statistical terms for the
feebleminded?
2. Matlab terminates by telling me 4 times:
xhost: unable to open display "iconic"
What´s it trying to do?
3. Nevertheless, optseq generates 2 files according to my specifications
for the output. The .dat-file looks like the trial ordering: 3 columns,
with the second determining trial conditions and the third event
duration in [s] for trials. The first column looks like the time axis in
[s], right? But why is there a negative value for duration of the last
event? And what does the log-file (i.e. tsearched, nsearched) tell me?
Many regards, TIA-
andreas
