[-iswpX bool]
    Endian swap condition for observation file X {F}

[-prefrX str]
    Float range for observation file X (before transforms) {all}

[-preirX str]
    Int range for observation file X {all}

[-frX str]
    Float range for observation file X (after transforms) {all}

[-irX str]
    Int range for observation file X {all}

[-srX str]
    Segment range for observation file X {all}

[-leftPadX unsigned]
    Prepend padding frames to file X {0}

[-rightPadX unsigned]
    Append padding frames to file X {0}

[-preprX str]
    Pre Per-segment frame Range for obs file X before any transforms are applied {null}

[-postprX str]
    Post Per-segment frame Range for obs file X after per-stream transforms are applied {null}

[-gpr str]
    Global Per-segment final frame Range {null}

[-justification str]
    Justification of usable frames (left, center, right) {left}

[-obsNAN bool]
    True if observation files allow FP NAN values {F}

File range options:

[-dcdrng str]
    Range to decode over segment file {all}

[-startSkip integer]
    Frames to skip at beginning (i.e., first frame is buff[startSkip]) {0}

[-endSkip integer]
    Frames to skip at end (i.e., last frame is buff[len-1-endSkip]) {0}

Help options:

[-help [unsigned]]
    Print this message. Add an argument from 1 to 5 for increasing help info. {1}

[-version bool]
    Print GMTK version number and exit. {F}

Observation matrix transformation options:

[-sdiffactX str]
    Action if different number of segments in streams: error (er), truncate from end (te), repeat last sent (rl), and wrap around (wa). {te}

[-cppifascii bool]
    Pre-process ASCII files using CPP {F}

[-transX str]
    per stream transformations string {null}

[-posttrans str]
    Final global transformations string {null}

[-comb str]
    Combine float features (none: no combination, add, sub, mul,div {none}

[-cppCommandOptions str]
    Command line options to give to 'cpp' {null}

Statistical options:

[-meanSubOnly bool]
    Only normalize for 0 mean rather 0 mean and unit variance {F}

Additional arguments:

[-argsFile <str>]
    File to obtain additional arguments from {}
