Hi,
Q1: Event related design
The experimental design that I'm working on has non trials between events.
eg:
A: event 1;
n: nontrial;
B:event 2;
TR=2 seconds;
Design: AnnnnnBnnnAnBnnnnnnnA
How should look the ideal file for this design:
Tp A B
1 1 0
2 0 0
3 0 0
4 0 0
5 0 0
6 0 0
7 0 1
8 0 0
9 0 0
10 0 0
11 1 0
12 0 0
13 0 1
14 0 0
15 0 0
16 0 0
17 0 0
The question is related to Timepoints 2 3 4 5 6 8 9 10 etc; will they enter the baseline OR should I specify n(nontrial) as a condition?
======================================
Q2: Block design
eg:
A: event 1;
n: nontrial;
TR=2 seconds;
Design: AnnnnnAnnnAnAnnnnnnnA
How should look the ideal file for this design:
Tp A
1 1
2 0
3 0
4 0
5 0
6 0
7 1
8 0
9 0
10 0
11 1
12 0
13 1
14 0
15 0
16 0
17 0
OR can the ideal file look like this:
Tp A
1 1
2 1
3 1
4 1
5 1
6 1
7 1
8 1
9 1
10 1
11 1
12 1
13 1
14 1
15 1
16 1
17 1
Question: Is it possible to perform a block design analysis having sometime non trials for 3 consecutive TRs (6 seconds)?
