Sxy.prn Link

The paper is written as if the file sxy.prn is a newly‑discovered data‑exchange format used in the field of synthetic biology for representing synthetic gene‑circuit designs. If sxy.prn refers to something else, you can replace the technical details while keeping the overall structure.

Method A – Ghostscript (works for both PostScript & PCL)

# Windows (using the Ghostscript executable)
gswin64c -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=sxy.pdf sxy.prn

# macOS / Linux
gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=sxy.pdf sxy.prn

Method B – Printfil (Windows GUI)

sxy.prn follows a line‑oriented, section‑based grammar. Each line is either a comment (#), a section header ([SECTION]), or a key‑value entry (KEY = VALUE). Sections can be nested via dot notation. Table 1 summarises the core sections.

| Section | Description | Example | |---------|-------------|---------| | [CIRCUIT] | Global circuit metadata | NAME = ToggleSwitch | | [CIRCUIT.COMPONENTS] | List of parts (ordered) | 1 = promoter: Ptet | | [CIRCUIT.INTERACTIONS] | Directed edges with logic | 1 = 2 : repression | | [PARTS.<ID>] | Metadata for a specific part | SEQUENCE = ATG… | | [SIMULATION] | Global simulation settings | TIME = 1000 | | [SIMULATION.INITIAL] | Initial concentrations | geneA = 10 nM | sxy.prn

Formal BNF (simplified)

file          ::=  line 
line          ::= comment | section | entry
comment       ::= "#"  any_char  EOL
section       ::= "[" identifier  "." identifier  "]" EOL
entry         ::= key "=" value EOL
key           ::= identifier
value         ::=  any_char_except_EOL 
identifier    ::= letter  letter 

The grammar is deliberately permissive; validation is performed by the reference parser. The paper is written as if the file sxy
