NAME - List information about SDFile(s)

SYNOPSIS SDFile(s)... [-a --all] [-c --count] [--chiral] [--datacheck] [-d --detail infolevel] [-e --empty] [-f, --fields] [-h, --help] [-i, --invalidatomnumbers] [-m, --mismatch] [-s, --salts] [-u, --unknownatoms] [-w, --workingdir dirname] SDFile(s)...


List information about SDFile(s) contents: number of compounds, empty records and so on. Multiple SDFile names are separated by spaces. The valid file extensions are .sdf and .sd. All other file names are ignored. All the SD files in a current directory can be specified either by *.sdf or the current directory name.


-a, --all

List all the available information.

-c, --count

List number of compounds. This is default behavior.


List number of empty atom/bond blocks for compounds with chiral flag set in count line.

-d, --detail infolevel

Level of information to print. Default: 1. Possible values: 1, 2, or 3.


List number of numerical and non-numerical values for each data field.

-e, --empty

List number of empty atom/bond blocks and data fields for compounds.

-f, --fields

List data field labels present for compounds.

-h, --help

Print this help message.

-i, --invalidatomnumbers

List number of bond blocks for compounds which contain invalid atom numbers.

-m, --mismatch

List number of atom/bond blocks for compounds which don't match with counts line information in header block.

-s, --salts

List number of atom blocks for compounds which contain salts identified as disconnected structural units.

-u, --unknownatoms

List number of atom blocks for compounds which contain special atom symbols such as L, Q, * ,LP, X, R#, or any other non periodic table symbols.

-w, --workingdir dirname

Location of working directory. Default: current directory.


To count compounds in SD file(s), type:

% Sample1.sdf
% Sample1.sdf Sample2.sdf
% *.sdf

To list all available information for SD file(s), type:

% -a *.sdf

To list all data fields present in sample.sdf, type:

% -f Sample.sdf

To count number of compounds which contain salts and list associated structural data, type:

% -s -d 3 Sample.sdf
