ASTRAN Process

To access this process:

See this process in the Command Table.

Process Overview

This process reads one or more ASCII sample assay files in SIF format and updates a DATAMINE database file by matching sample numbers. Up to 10 grade fields may be updated from each file.

ASTRAN expects to find a file ASTRAN.LST containing a list of SIF files to be processed. This file may be prepared by an operating system pre-processing script. Any files that have all records matched are renamed.

SIF files that do not have all their samples matched will be rewritten with a flag 'MATCHED: date' at the end of any matched records. On subsequent runs these previously matched records may be ignored or rematched according to the value of the @UPDATE parameter.

A database file &XREF is used to cross reference assay names as they appear in the SIF files (ASSNAM) and the database field name (ELEMENT). Multiple values of ASSNAM may be referenced to a field. This file also has a units field which specifies the units of the assay as stored in the database. Assays in the SIF file will be converted to match these units. Only one value of units should appear in &XREF for each value of ELEMENT.

Example of &XREF:

=======================
ELEMENT UNITS ASSNAM
=======================
AU1 ppm Au
AU2 ppm Au(R)
AU2 ppm Au(R)
SULPHUR % S

A 2 valued DATAMINE environment variable ASTRAN_COMMAND is used by ASTRAN.

The first value is an operating system command or script to be run to pre-process the ASCII files and produce the ASTRAN.LST file.

The second value gives the format of the command to be used to rename a fully matched file. Each individual file name will be substituted for the $1.

Input Files

Name

Description

I/O Status

Required

Type

IN

Input database file.

This file must contain a sample identifier field. The default name for this field is SAMPLEID.

It may be either Numeric or Alphanumeric. In addition, the IN file will contain a number of other fields: the names of elements and compounds to be matched with fields in the assay data files. It may also contain fields which are not matched such as BHID, FROM, TO, etc.

Input

Yes

Table

XREF

Required assay name cross-reference file.

 This file is used to link the names of assay fields in the database file to fields in the assay transfer {SIF} file. It is also used to convert results from the assay file to database units.

Required fields in the XREF file are:

  • ELEMENT -- name of field in the IN file. Alphanumeric; two words.

  • UNITS -- units stored in the IN file for the current field. Alphanumeric; one word. Allowable units are: '%' -- per cent. ppm -- parts per million. ppb -- parts per billion.

  • ASSNAM -- name of field in assay transfer file. Alphanumeric; two words. There must be at least one record for each assay field in the IN file. There must be one record for each alias of a given assay field. An assay transfer file may not reference an assay field more than once for a given job.

Input

Yes

Example

The following line would appear in one of the DATAMINE environment files.

ASTRAN_COMMAND = 'ls -c eg* > ASTRAN.LST',
'mv $1 matched/$1.M'

SIF: As required by ASTRAN.

ASTRAN expects the SIF file to comprise ASCII records of no more than 124 characters. These include 6 lines of leader followed by any number of data records containing sample number and up to 10 assays. Blank lines may precede the header.

Line 1 of Header

JOB, nSAM mSNR cCOL

where

JOB - Job code terminated by a comma.
n - Number of sample records.
m - Number of samples not recorded.
c - Number of assay columns present.

The last 3 fields may be separated by a number of spaces.

Line 2 of Header

COL
1 - 20 ignored
21 - 26 6 digit date in format ddmmyy
27 - 107 up to 10 fields 24 characters wide with left justified assay name.

Line 3 of Header

COL
1 - 26 ignored
20 - 107 up to 10 fields 24 characters wide containing units. One of %, ppm, ppb, PPM, PPB.
Line 4-6 of Header
3 lines ignored.

Line 7 - End of File

COL
1 - 10 sample alpha code.
11 - 26 sample numeric code.
27 - 107 up to 10 fields 24 characters wide containing assay results.

Note: For data fields:

All blank becomes missing value.
7 spaces L becomes trace.
7 spaces - becomes missing value.

If sample number has ** in cols 11-12 samples treated as not received.
