NAME
nauty-copyg - convert format and select subset
SYNOPSIS
copyg [-gszfp#:#qhx] [infile [outfile]]
DESCRIPTION
Copy a file of graphs with possible format conversion.
|
-g |
Use graph6 format for output |
|||
|
-s |
Use sparse6 format for output |
|||
|
-z |
Use digraph6 format for output |
|||
|
-i |
Use incremental sparse6 format for output |
In the absence of -g, -s, -z or -i, the format depends on the header or, if none, the first input line. As an exception, digraphs are always written in digraph6.
|
-p# -p#:# |
Specify range of input lines (first is 1) This can fail if the input has incremental lines.
|
-f |
||||
|
With -p, assume input lines of fixed length |
(ignored if header or first line has sparse6 format).
|
-I# |
Have at most this number of incremental steps |
in a row.
Implies -i.
|
-h |
Write a header. |
|||
|
-x |
Don’t write a header. |
In the absence of -h and -x, a header is written if there is one in the input.
|
-q |
Suppress auxiliary output. |
