Please read the following carefully about group analysis setup:
1. If the resolution of your EPI data is near n millimeters, during Talairach conversion use
"the command adwarp -dxyz n" to greatly reduce runtime without sacrificing accuracy.
2. We strongly suggest that factor names be labeled with short (2 or 3 capital letters) names
so that subbrik labels can be shown on AFNI viewer.
3. With nesting, arrange your design in such a way that the last factor is nested within the 1st factor.
4. Each input file should include only one subbrik. We suggest files be
named by reflecting the hierarchy of the experiment design.
5. Currently all of the following terms are modeled: main effects and applicable interactions in various orders, .
Groups analysis for volume or surface data (0 - volume; 1 - surface)? 1
Input files have to be in 1D format, and program @Purify_1D can be used to extract each regressor
coefficient column to a 1D file. Type @Purify_1D for usage ...
Which column corresponds to regressor coefficient in the 1D files? (1, 2, 3, ...) 23
How many number of nodes in the surface data? 198811
How many factors? 1
Available design types:
Type 1: one factor with fixed effect.
Choose design type (1, 2, 3, 4, 5): 1
Is the design balanced? (1 - Yes; 0 - No) 1
Label for No. 1 factor: Group
How many levels does factor A (Group) have? 2
Label for No. 1 level of factor A (Group) is: Controls
Label for No. 2 level of factor A (Group) is: Patients
Enter the sample size (number of observations) per combination: 3
All input files are supposed to contain only one subbrik.
Please provide input files.

Total slices along Z axis: 4 - You can estimate the total runtime
by multiplying the runtime for each slice from down below.
