nauty-copyg - convert format and select subset
copyg [-gszfp#:#qhx] [infile
[outfile]]
- 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.
