The parameters for MAKESHOWPLAY are listed below. Parameters within brackets [] are optional; they are only needed if you have two block conditions.

STIMLIST - a text file name that contains a list of stimulus events. If the file is not in your current working directory you must specify the directory path needed to find that file.

FLAG (combine by addition):
   1 - Set response flag for every stimulus
   2 - Randomize stimuli (use all before repeating)
   4 - Do stimuli once in order and then randomize repeats
   8 - Do not prepend SHOWPLAY parameter lines to beginning of output
  16 - replace images without erasing
  32 - set font for large text
  64 - oscillate stimuli (back and forth through list)
 128 - test mode (turn off disdaqs and don't save output)
 256 - reset time base at end of stimulus list
 512 - use 8 bits to store images (grey scale only)
1024 - use stimulus number as user_code

TRIAL_MS   - The duration of each stimulus trial (in msecs)
GAP_MS     - The delay interval after one trial, before the next.
TOTSECS    - The total duration of the paradigm (in secs).
BLKTRIALS  - The number of stimulus trials in each block of condition 1.
STIMLIST2  - Like STIMLIST, for condition 2.
TRIAL2_MS  - Like TRIAL_MS, for condition 2.
BLKTRIALS2 - Like BLKTRIAL, for condition 2.

To save the results of MAKESHOWPLAY as a new file, you should redirect the text output using the '> filename' syntax. For example,

makeshowplay list1.txt 0 1000 0 300 6 list2.txt 1000 6 > test.txt
