plugout_drive


Usage: plugout_drive [-host name] [-v]

This program connects to AFNI and sends commands
 that the user specifies interactively or on command line
 over to AFNI to be executed.

NOTE:
 If you quit plugout_drive and then re-start it immediately
 (as in a script), you might run into problems re-connecting
 to AFNI. The reason is that the TCP/IP system doesn't hang
 up a socket instantly when commanded to do so; the socket
 takes about a second to close down completely. If you are
 writing a script that starts plugout_drive repeatedly, you
 should insert a command 'sleep 1' between each start, to
 give the operating system time to clean the socket up.
 Otherwise, AFNI might not be able to open the socket,
 and plugout_drive will output an error message:
   ** AFNI didn't like control information!

OPTIONS:
  -host name    Means to connect to AFNI running on the computer
                'name' using TCP/IP.  The default is to connect
                on the current host 'localhost' using TCP/IP.

  -shm          Means to connect to the current host using shared
                memory.  There is no reason to do this unless
                you are transferring huge quantities of data.
                N.B.:  '-host .' is equivalent to '-shm'.

  -v            Verbose mode.

  -port pp      Use TCP/IP port number 'pp'.  The default is
                8099, but if two plugouts are running on the
                same computer, they must use different ports.
                For a list of currently used ports use afni -list_ports

  -maxwait t    Wait a maximum of 't' seconds for AFNI to connect;
                if the connection doesn't happen in that time, exit.
                [default wait time is 9 seconds]

  -name sss     Use the string 'sss' for the name that AFNI assigns
                to this plugout.  The default is something stupid.

  -com 'ACTION DATA'  Execute the following command. For example:
                       -com 'SET_FUNCTION SomeFunction'
                       will switch AFNI's function (overlay) to
                       dataset with prefix SomeFunction.
                      Make sure ACTION and DATA are together enclosed
                       in one pair of single quotes.
                      There are numerous actions listed in AFNI's
                       README.driver file.
                      You can use the option -com repeatedly.

  -quit         Quit after you are done with all the -com commands.
                The default is for the program to wait for more
                commands to be typed at the terminal's prompt.

NOTES:
You will need to turn plugouts on in AFNI using one of the
following methods:
 1. Including '-yesplugouts' as an option on AFNI's command line
 2. From AFNI GUI: Define Datamode->Misc->Start Plugouts
 3. From AFNI GUI: Press the 'NIML+PO' button (near 'Overlay')
 4. Set environment variable AFNI_YESPLUGOUTS to YES in .afnirc
Otherwise, AFNI won't be listening for a plugout connection.
  [AFNI doesn't listen for socket connections, unless]
  [it is told to,  in order to avoid the overhead of]
  [checking for incoming data every few milliseconds]

This program's exit status will be 1 if it couldn't connect
to AFNI at all.  Otherwise, the exit status will be 0.
You could use this feature in a script to check if a copy of
AFNI is ready to rumble, and if not then start one, as in the
following csh fragment:
    plugout_drive -maxwait 1 -com 'OPEN_WINDOW axialimage'
    if( $status == 1 )then
      afni -yesplugouts &
      sleep 2 ; plugout_drive -com 'OPEN_WINDOW axialimage'
    endif

To have different plugout_* programs talking to different
AFNI, use the -np* options below
   -np PORT_OFFSET: Provide a port offset to allow multiple instances of
                    AFNI <--> SUMA, AFNI <--> 3dGroupIncorr, or any other
                    programs that communicate together to operate on the same
                    machine.
                    All ports are assigned numbers relative to PORT_OFFSET.
         The same PORT_OFFSET value must be used on all programs
           that are to talk together. PORT_OFFSET is an integer in
           the inclusive range [1025 to 65500].
         When you want to use multiple instances of communicating programs,
           be sure the PORT_OFFSETS you use differ by about 50 or you may
           still have port conflicts. A BETTER approach is to use -npb below.
   -npq PORT_OFFSET: Like -np, but more quiet in the face of adversity.
   -npb PORT_OFFSET_BLOC: Similar to -np, except it is easier to use.
                          PORT_OFFSET_BLOC is an integer between 0 and
                          MAX_BLOC. MAX_BLOC is around 4000 for now, but
                          it might decrease as we use up more ports in AFNI.
                          You should be safe for the next 10 years if you
                          stay under 2000.
                          Using this function reduces your chances of causing
                          port conflicts.

         See also afni and suma options: -list_ports and -port_number for
            information about port number assignments.

         You can also provide a port offset with the environment variable
            AFNI_PORT_OFFSET. Using -np overrides AFNI_PORT_OFFSET.

   -max_port_bloc: Print the current value of MAX_BLOC and exit.
                   Remember this value can get smaller with future releases.
                   Stay under 2000.
   -max_port_bloc_quiet: Spit MAX_BLOC value only and exit.
   -num_assigned_ports: Print the number of assigned ports used by AFNI
                        then quit.
   -num_assigned_ports_quiet: Do it quietly.

     Port Handling Examples:
     -----------------------
         Say you want to run three instances of AFNI <--> SUMA.
         For the first you just do:
            suma -niml -spec ... -sv ...  &
            afni -niml &
         Then for the second instance pick an offset bloc, say 1 and run
            suma -niml -npb 1 -spec ... -sv ...  &
            afni -niml -npb 1 &
         And for yet another instance:
            suma -niml -npb 2 -spec ... -sv ...  &
            afni -niml -npb 2 &
         etc.

         Since you can launch many instances of communicating programs now,
            you need to know wich SUMA window, say, is talking to which AFNI.
            To sort this out, the titlebars now show the number of the bloc
            of ports they are using. When the bloc is set either via
            environment variables AFNI_PORT_OFFSET or AFNI_PORT_BLOC, or
            with one of the -np* options, window title bars change from
            [A] to [A#] with # being the resultant bloc number.
         In the examples above, both AFNI and SUMA windows will show [A2]
            when -npb is 2.


Global Options (available to all AFNI/SUMA programs)
  -h: Mini help, at time, same as -help in many cases.
  -help: The entire help output
  -HELP: Extreme help, same as -help in majority of cases.
  -h_view: Open help in text editor. AFNI will try to find a GUI editor
  -hview : on your machine. You can control which it should use by
           setting environment variable AFNI_GUI_EDITOR.
  -h_web: Open help in web browser. AFNI will try to find a browser.
  -hweb : on your machine. You can control which it should use by
          setting environment variable AFNI_GUI_EDITOR.
  -h_find WORD: Look for lines in this programs's -help output that match
                (approximately) WORD.
  -h_raw: Help string unedited
  -h_spx: Help string in sphinx loveliness, but do not try to autoformat
  -h_aspx: Help string in sphinx with autoformatting of options, etc.
  -all_opts: Try to identify all options for the program from the
             output of its -help option. Some options might be missed
             and others misidentified. Use this output for hints only.

   -overwrite: Overwrite existing output dataset.
               Equivalent to setting env. AFNI_DECONFLICT=OVERWRITE
   -ok_1D_text: Zero out uncommented text in 1D file.
                Equivalent to setting env. AFNI_1D_ZERO_TEXT=YES
   -Dname=val: Set environment variable 'name' to value 'val'
             For example: -DAFNI_1D_ZERO_TEXT=YES
   -Vname=: Print value of environment variable 'name' to stdout and quit.
            This is more reliable that the shell's env query because it would
            include envs set in .afnirc files and .sumarc files for SUMA
            programs.
             For example: -VAFNI_1D_ZERO_TEXT=
   -skip_afnirc: Do not read the afni resource (like ~/.afnirc) file.
   -pad_to_node NODE: Output a full dset from node 0 to MAX_NODE-1
                   ** Instead of directly setting NODE to an integer you
                      can set NODE to something like:
                   ld120 (or rd17) which sets NODE to be the maximum
                      node index on an Icosahedron with -ld 120. See
                      CreateIcosahedron for details.
                   d:DSET.niml.dset which sets NODE to the maximum node found
                      in dataset DSET.niml.dset.
                   ** This option is for surface-based datasets only.
                      Some programs may not heed it, so check the output if
                      you are not sure.
   -pif SOMETHING: Does absolutely nothing but provide for a convenient
                   way to tag a process and find it in the output of ps -a
   -echo_edu: Echos the entire command line to stdout (without -echo_edu)
              for edification purposes

   SPECIAL PURPOSE ARGUMENTS TO ADD *MORE* ARGUMENTS TO THE COMMAND LINE
------------------------------------------------------------------------
   Arguments of the following form can be used to create MORE command
   line arguments -- the principal reason for using these type of arguments
   is to create program command lines that are beyond the limit of
   practicable scripting. (For one thing, Unix command lines have an
   upper limit on their length.) This type of expanding argument makes
   it possible to input thousands of files into an AFNI program command line.

   The generic form of these arguments is (quotes, 'single' or "double",
   are required for this type of argument):
     '<<XY list'
   where X = I for Include (include strings from file)
      or X = G for Glob (wildcard expansion)
   where Y = M for Multi-string (create multiple arguments from multiple strings)
      or Y = 1 for One-string   (all strings created are put into one argument)

   Following the XY modifiers, a list of strings is given, separated by spaces.
   * For X=I, each string in the list is a filename to be read in and
       included on the command line.
   * For X=G, each string in the list is a Unix style filename wildcard
       expression to be expanded and the resulting filenames included
       on the command line.
   In each case, the '<<XY list' command line argument will be removed and
   replaced by the results of the expansion.

  * '<<GM wildcards'
    Each wildcard string will be 'globbed' -- expanded from the names of
    files -- and the list of files found this way will be stored in a
    sequence of new arguments that replace this argument:
      '<<GM ~/Alice/*.nii ~/Bob/*.nii'
    might expand into a list of hundreds of separate datasets.
    * Why use this instead of just putting the wildcards on the command
      line? Mostly to get around limits on the length of Unix command lines.

  * '<<G1 wildcards'
    The difference from the above case is that after the wildcard expansion
    strings are found, they are catenated with separating spaces into one
    big string. The only use for this in AFNI is for auto-catenation of
    multiple datasets into one big dataset.

  * '<<IM filenames'
    Each filename string will result in the contents of that text file being
    read in, broken at whitespace into separate strings, and the resulting
    collection of strings will be stored in a sequence of new arguments
    that replace this argument. This type of argument can be used to input
    large numbers of files which are listed in an external file:
      '<<IM Bob.list.txt'
    which could in principle result in reading in thousands of datasets
    (if you've got the RAM).
    * This type of argument is in essence an internal form of doing something
      like `cat filename` using the back-quote shell operator on the command
      line. The only reason this argument (or the others) was implemented is
      to get around the length limits on the Unix command line.

  * '<<I1 filenames'
    The difference from the above case is that after the files are read
    and their strings are found, they are catenated with separating spaces
    into one big string. The only use for this in AFNI is for auto-catenation
    of multiple datasets into one big dataset.

  * 'G', 'M', and 'I' can be lower case, as in '<<gm'.

  * 'glob' is Unix jargon for wildcard expansion:
    https://en.wikipedia.org/wiki/Glob_(programming)

  * If you set environment variable AFNI_GLOB_SELECTORS to YES,
    then the wildcard expansion with '<<g' will not use the '[...]'
    construction as a Unix wildcard. Instead, it will expand the rest
    of the wildcard and then append the '[...]' to the results:
      '<<gm fred/*.nii[1..100]'
    would expand to something like
      fred/A.nii[1..100] fred/B.nii[1..100] fred/C.nii[1..100]
    This technique is a way to preserve AFNI-style sub-brick selectors
    and have them apply to a lot of files at once.
    Another example:
      3dttest++ -DAFNI_GLOB_SELECTORS=YES -brickwise -prefix Junk.nii \
                -setA '<<gm sub-*/func/*rest_bold.nii.gz[0..100]'

  * However, if you want to put sub-brick selectors on the '<<im' type
    of input, you will have to do that in the input text file itself
    (for each input filename in that file).

   * BE CAREFUL OUT THERE!
