limits specify limits of input map to be bricked

brick specifies dimensions of fmt2 formatted bricks

scale scale for density values before before storing in bricked file

MAKBRK 1 file format code

fmt1 UCSD format for FRODO file

fmt2 Cambridge format for FRODO file¹

2 byte swap option²

nosw bytes of the density map will not be swapped

swap bytes of words in output bricked map swapped

1 This field will serve as a background map (Map 1-Map 4).

2 This option allows the brick map to be transferred to machines with a reversed addressing scheme. (i.e. high order bits are stored as low order bits on the destination machine) in order to run FRODO.

limits 1 min x map grid coordinate to be bricked

2 max x map grid coordinate to be bricked

3-4 same as 1-2 for y coordinate

5-6 same as 1-2 for z coordinate

Default is for total input map to be bricked.

brick 1-3 brick size along x, y, z in grid units 8, 8, 8

Only used for fmt2 format.

scale 1 scale factor applied to integerized density values

By default all brick map values are between 0 and 10.
