### SYNOPSIS

> ndrio [-help]
> [-NET | -NDR | -PNML | -TPN]
> [-net | -ndr | -pnml [-tpnty | -ptty | -mcc] | -tpn | -pnt | -romeo | -lola | -nupn]
> [-graphplace | -dot | -neato | -circo | -textify]
> [-no-nupn] [-ren] [-d] [-a] [-rev] [-t]
> [infile] [outfile] [errorfile]

### DESCRIPTION

> ndrio converts Petri nets and Time Petri nets between several, graphic or textual, formats. ndrio handles tina labels, delay intervals associated with transitions, generalized inhibitor and read (test) arcs, generalized stopwatch-inhibitor and stopwatch arcs, and priorities. The features not supported by the target format are silently omitted. The formats manipulated are the following:

>     name            extension       description
>     ------------------------------------------------------
>     net             .net          tina textual format
>     ndr             .ndr          tina graphic format (produced by nd)
>     tpn             .tpn          tina textual scripts format
>     pnml            .pnml         Petri Net Markup Language format
>                                     (with or without graphics)
>     pnt             .pnt          INA format
>                                     (if the net is timed, the intervals
>                                      are saved into a companion .tim file)
>     romeo           .romeo        romeo format (without graphics)
>     lola            .lola         LoLA format (unstructured)
>     nupn            .nupn         CADP nupn format

> The conversions currently supported are the following:

>     from            to
>     ------------------------------------------------------
>     net             ndr, tpn, pnml, pnt, romeo, lola, nupn
>     ndr             net, tpn, pnml, pnt, romeo, lola, nupn
>     tpn             net, ndr, pnml, pnt, romeo, lola, nupn
>     pnml            net, ndr, tpn, pnml, pnt, romeo, lola, nupn

### OPTIONS

> -help | Recalls options.
> Input format flags:
> -NET | -NDR | -PNML | -TPN
> | Specifies the format of the input net. This flag is necessary when the input net is read on standard input, or read from a file that does not bear the expected extension. Default is -NET.
> Output format flags:
> -net | -ndr | -pnml | -tpn | -pnt | -romeo | -lola | -nupn
> | Specifies the format of the output net. This flag is necessary when the output net is written on standard output, or into a file that does not bear the expected extension. Export to romeo and lola is preliminary. The graphic information, if any, is currently not exported to romeo. Also, the user should make sure the place and transition names used in the input file are legal romeo or lola names; ndrio does not attempt to convert them (consider passing options -r -d, in addition). Export to nupn converts pnml format, with or without nupn units descriptions, to CADP nupn format. If the input file format is not pnml, or there are no unit descriptions in the file, or if option -no-nupn is passed, outputs a file in nupn format in which all units are trivial (each contains a single place). In all cases, the input net is assumed safe.
> Secondary pnml output flags:
> -tpnty | -ptty | -mcc
> | By default (-tpnty), ndrio generates pnml in the "tpn" profile proper to TINA. With -ptty, it generates pnml conformimg to the Place/Transition profile. That is temporal interval, special arcs, labels, notes are dropped from the input. In both cases ndrio generates unique xml ids for places and transitions. With -mcc, ndrio generates pnml obeying the Model Checking Contest convention that the xml id of each node is equal to its pnml name. The conversion fails then if some name is not a syntactically legal xml id, in which case you may wish to rename the net first by -ren -d.
> Drawing options:
> -graphplace | -dot | -neato | -circo
> | Specify a placement filter for nodes. Necessary when converting from a graphics-free format into .ndr; optional when converting into .pnml (graphics information is only generated if some filter is specified). When converting from a graphic format, the original placement information is always retained, whatever the tool specified.
> Textifying option:
> -textify | Removes any graphics information from the input file when graphics is supported but optional in the output format.
> Other flags:
> -no-nupn | If the input file is in pnml format, forget any nupn units descriptions in it.
> -ren | -r | Renames places and transitions with integers (from 1) prefixed by "p" and "t", respectively. Old names become labels.
> -d | Drops all labels of places and transitions.
> -a | Drops all annotations.
> -rev | Reverses the direction of normal edges (inhibitor, read, stopwatch, stopwatch-inhibitor and priority edges are unchanged).
> -transpose | -t
> | When the output format is .net, prints the .net description "by place" instead of the default "per transition" presentation. The net itself is unchanged.
> Input source:
> infile | Where the net is read. The input format is determined by the file type, according to the table above. If absent or specified by "-", the net is read on standard input in the format specified by the input flag. If both an infile and some input flag are present, then the format defined by the input flag supersedes that determined by the infile extension.
> Output destination:
> outfile
> | Where the net is written. The output format is determined by the file type, according to the table above. If absent or specified by "-", then the net is written on standard output in the format specified by the output flag. If both an outfile and some output flag are present, then the format defined by the output flag supersedes that determined by the outfile extension.
> Errors destination:
> errorfile
> | Where error messages are written. By default, errors are printed on standard error.
