Dear DCM experts
i have one subject ( patient) which i've recorded his data in two days. and in each day i've recorded his data in 27 times with specify task because I couldn't recording his data in the long time and he needed to rest. for this reason i recorded his data intervals of 140 second with specified task ( left hand movement- right hand movement and inspiration) all tasks were performed in block fashion consisting of 3 ON and 4 OFF phases of 20 second duration each. for example for first session his task was 20s relax - 20s left-hand -20 s relax-20s left-hand-20s relax -20 left-hand- 20s relax .and after 5 minute rest my recording again started by new task or as last task. and in the another day i recorded data exactly same as first day.i think it's better that i say, i have 54 sessions.
i've defined the GLM, specifed and estimated contrasts and specifed the coordinate of my interest perfectly, but when i click the eigenvariate for define the VOIs , i have two problems.
1- i don't know why , when the software ask "which session" only show the 46
for maximum.instead of 54.
2- i don't know how can i put only one VOI for all of session at a time.
in some messages, it was recommended that it's better to concatenate all
data but i want to know somebody knows another option without concatenate
the data.
thanks for your help in advance
All the best
