Properties

AMAX: number

maximum density value

AMEAN: number

mean/average density value

AMIN: number

minimum density value

ARMS: number

rms deviation of map from mean density

ISPG: number

space group number

LSKFLG: number

flag for skew transformation, =0 none, =1 if foll

MACHST: number[]

Machine stamp indicating machine type which wrote file, 17 and 17 for big-endian or 68 and 65 for little-endian.

MAP: string

Character string 'MAP ' to identify file type

MAPC: number

axis corresponds to columns (1,2,3 for X,Y,Z)

MAPR: number

axis corresponds to rows (1,2,3 for X,Y,Z)

MAPS: number

axis corresponds to sections (1,2,3 for X,Y,Z)

MODE: number

0 image : signed 8-bit bytes range -128 to 127 1 image : 16-bit halfwords 2 image : 32-bit reals 3 transform : complex 16-bit integers 4 transform : complex 32-bit reals 6 image : unsigned 16-bit range 0 to 65535 16 image: unsigned char * 3 (for rgb data, non-standard)

Note: Mode 2 is the normal mode used in the CCP4 programs. This parser only supports modes 0 and 2

NC: number

number of columns (fastest changing)

NCSTART: number

first column

NR: number

number of rows

NRSTART: number

first row

NS: number

number of sections (slowest changing)

NSSTART: number

first section

NSYMBT: number

number of bytes used for storing symmetry operators

intervals along x

NY: number

intervals along y

NZ: number

intervals along z

SKWMAT: number[]

Skew matrix S (in order S11, S12, S13, S21 etc) if LSKFLG .ne. 0 May be used in CCP4 but not in MRC

SKWTRN: number[]

Skew translation t if LSKFLG != 0 Skew transformation is from standard orthogonal coordinate frame (as used for atoms) to orthogonal map frame, as Xo(map) = S * (Xo(atoms) - t)

May be used in CCP4 but not in MRC

alpha: number

alpha cell angle (Degrees)

beta: number

beta cell angle (Degrees)

gamma: number

xLength: number

x axis cell length (Angstroms in CCP4)

yLength: number

y axis cell length (Angstroms in CCP4)

zLength: number

z axis cell length (Angstroms in CCP4)
