fScan Reference Manual, Chapter 1 (Introduction): textformats

Text Formats -- File formats recognized in fScan

Mult-column tables

Task condition lists - Multi-column timing file (with optional column header line)

 Onset   Code      (default format)
   Onset - time in seconds when this condition started
   Code - number or name of this condition

 By default, each condition is assumed to continue until the next onset time unless 
   a duration is specified.
 If the first line of the file is non-numeric it is treated as a column header line.
 If a header line is specified, columns can be in whichever order is specified in the header.
 Valid column names are: onset, code, duration

Physiological data files - 2-column waveform recordings

 Time    Value
   Time - time in seconds for this data value
   Value - waveform data value

Matrix file - single or multi-column numerical data

 The dimensions of the data object are taken from the column format of the file itself.
 The meaning of the data table depend on its usage context.
 Examples:
   Convolution kernel - NxN weighting table used in "-expr convolve" command.
   Map lookup table - 2-column table used in "-expr map" command.
   Color lookup table - 4-column color lookup table
     Index   Red    Green   Blue
       Index - the voxel value associated with this color
       Red - Amount of red in this color (0-255)
       Green - Amount of green in this color (0-255)
       Blue - Amount of blue in this color (0-255)
     All values in the file are numbers.
     Lines in the table should be in order of increasing Index values.
     Index values do not need to be continuous -- colors will be automatically 
     interpolated for any index value  between those appearing in the table. 
     Any voxel values higher than the highest index value will be shown with the 
     highest value's color.
   FSL schedules - 3-column event timing file describing a single task parameter 
     Onset   Duration  Weight
       Onset - time in seconds when the condition/parameter started
       Duration - duration of the condition in seconds 
       Weight - a weighting factor for this condition epoch (typically 1.0)
     All values in the file are numbers.
     Each line in the schedule file describes an epoch of the given parameter.
     Multiple schedule files are used to describe the timing of multiple parameters.

XML files
