MakeDesign

Generate a design file from various parameters and (optionally) a datafile.

Invocation

java MakeDesign [datafile]

This starts up the java interpreter and runs the MakeDesign application. You need to have set up your environment for java in order for this to work.

MakeDesign window

Information to be entered

Output file
Filename to use in writing the resulting design file. Give full path to create it somewhere other than in the current working directory.
Design parameters
- Number of scans per trial
  Number of scans (images) acquired during each trial. Each line in the design file is duplicated this number of times so that it will line up with the list of images.
- Number of trials per block
  Number of trials in each block (or each Pfile).
- Number of blocks
  Number of total blocks. Entering a number here is optional if a datafile is given as input.
- Determine number of blocks from datafile
  Check this box if you want the program to determine the number of blocks based on the number of trials in the datafile and the number of trials per block given. This option is only available if a datafile is given, otherwise the number of blocks must be specified.
Columns to include in design file
- Subject
  Check this box and enter a value if you would like a subject column. The value entered will be put on every row in the design file.
- Block, with prefix
  Check this box if you would like a column identifying each block number with the given prefix. All trials in the first block will be labeled block01, the second block with block02, and so on. Any text (or no text) can be entered as the prefix.
- Trial, with prefix
  Similarly to the block column, this column identifies each trial within a block. Trial counting resets to 1 at the beginning of each new block.
- Columns from datafile
  Check this box and enter the name of a datafile if you would like columns from the datafile to be included in the design file, or if you would like the datafile to determine the number of blocks in the design file. You should also indicate whether this is a PsyScope datafile or a raw (plain text, no headers or footers) datafile.
- Scan, with prefix
  Check this box if you would like a column specifying what scan each line in the design file corresponds to.
- Images from directory
  Check this box and select a directory with images (or a file with image filenames) if you would like to add a column of image filenames to the design file.
