# nauty-assembleg(1)

assemble input graphs as components of output graphs

## NAME

nauty-assembleg - assemble input graphs as components of output graphs

## SYNOPSIS

**assembleg** *-n#\|-n#:#* \[*-i#\|i#:#*\] \[*-k#\|k#:#*\] \[*-L*\] \[*-q*\] \[*-c*\] \[*infile* \[*outfile*\]\]

## DESCRIPTION

-

  Assemble input graphs as components of output graphs.

-

  The output file has no header. If the input has any directed graphs, all outputs are directed. Otherwise, the output format is determined by the header

-

  or first input.

-

  The input graphs had better all fit into memory at once,

-

  unless **-L** is given, in which case only the graphs of at most half the output size are stored at once.

-

  The output graphs will be non-isomorphic if the input

-

  graphs are connected and non-isomorphic.

- **-n**# **-n**#:#

  Give range of output sizes (compulsory)

- **-i**# **-i**#:#

  Give range of input sizes to use

- **-k**# **-k**#:#

  How many input graphs to combine (default **-k2**:)

- **-L**

  Assume all input graphs strictly larger than maxn/2

-

  vertices follow any smaller graphs in the input, where maxn is the largest size specified by **-n**. This can greatly reduce memory consumption.

- **-c**

  Also write graphs consisting of a single input

-

  (equivalent to **-k1**:, overridden by **-k**)

- **-u**

  Generate the graphs but don't write them

- **-q**

  Suppress auxiliary information.
