ct2db - manual page for ct2db 2.7.2

SYNOPSIS
ct2db [OPTIONS] [<input0.ct>] [<input1.ct>]...

DESCRIPTION
ct2db 2.7.2

Produce dot bracket notation of an RNA secondary structure from Zuker's .ct file

This program converts connectivity table (.ct) files into extended FASTA format with dot-bracket string.

-h, --help
    Print help and exit

--detailed-help
    Print help, including all details and hidden options, and exit

--full-help
    Print help, including hidden options, and exit

-V, --version
    Print version and exit

-p, --no-pk
    Remove pseudoknots from structure

    (default=off)

-m, --no-modified
    Do not keep modified bases, i.e. replace all non-canonical nucleotides with N.

    (default=off)

-v, --verbose
    Be verbose.

    (default=off)

--fasta-header=STRING
    Overwrite FASTA header with user-provided string.

    The name of the sequence (+structure pair) is usually extracted automaticall from the connectivity table header. Whenever such name is not present or the user wants to replace the sequence identifier, this parameter option can be used to do exactly that. Note, however, that for multiple structures in the input the same FASTA header will appear for all of the FASTA output lines.

--fh-from-filename[=replace|prepend|append]
    Use input file name as output FASTA header.

    (default=`replace')

    This only works when the input is not stdin but actual file names. By default, any (default) FASTA header will be replaced by the (truncated) input file name. Use the optional arguments "prepend" and "append" if you want the existing FASTA header to be prepended or appended by the input file name instead.

--filename-suffix=STRING
    The filename suffix to remove when turning the filename into a FASTA header.

    (default=`.ct')

    Provide an empty string to not truncate the filename at all.

--log-level=level
    Set log level threshold. (default=`2')

    By default, any log messages are filtered such that only warnings (level 2) or errors (level 3) are printed. This setting allows for specifying the log level threshold, where higher values result in fewer information. Log-level 5 turns off all messages, even errors and other critical information.

--log-file[=filename]
    Print log messages to a file instead of stderr. (default=`ct2db.log')

--log-time
    Include time stamp in log messages.

    (default=off)

--log-call
    Include file and line of log calling function.

    (default=off)
