Import ioGAS Point Data

Use the Import ioGAS Point Data menu option to import a single lab assay batch to a database. The data must currently be contained in an ioGAS *.GAS file.

Import ioGAS Point Data dialog options

Input ioGAS (.gas) file	Specify the GAS file (*.gas) from which to import the data. This is a required field. Script Parameter: CHIOGAS.FILE
Template	Specify the name of an import template that will be used to describe the data format. If the template does not exist for the input file, a new template will be created using the settings chosen in the import wizard dialogs. The new template file will have the same file name as the input file. If the template does exist, it will be used to establish the starting set-up of the import wizard. Script Parameter: CHIOGAS.TEMPLATE
Lab ID	Select the Lab ID from the drop-down list. If the Lab ID does not exist in the list, it will be added automatically. Use the [Lab IDs] button to manage the list by adding or deleting items. The list is stored in file ch_lab_id.lst in the GEOSOFT folder. The Lab ID will be placed in a channel of the database. Script Parameter: CHIOGAS.LAB_ID
Assay method	Select the assay method from the drop-down list. If the method does not exist in the list, it will be added automatically. Use the [Assays] button to manage the list by adding or deleting items. The method list is stored in file ch_assay_method.lst in the GEOSOFT folder. The selected method will be placed in the channel attributes. Script Parameter: CHIOGAS.ASSAYMETHOD
Weight	Specify the sample weight if known. The weight will be placed in a channel of the database. Script Parameter: CHIOGAS.WEIGHT
Channel attribute file (.csv)	If specified, the assay channel attributes are set automatically from the values contained in the CSV file. This file may be created from, or imported manually into an existing assays database using the Import Attributes and Set Attributes (found in the Geochem Import / Assay Attributes menu). Script Parameter: CHIOGAS.ATTR_FILE
Convert negatives	If "No", negative values are imported as is, without reference to any detection limit currently set for a given assay channel. If "Yes", then if the detection limit is set for the channel, any value less than the detection limit (including those less than 0.0) is replaced with a value equal to one-half the detection limit. Script Parameter: CHIOGAS.CONVNEG (0:No, 1:Yes)

Application Notes

After the first dialog, the Geochemistry Import Wizard is opened; use these dialogs to specify how the data in the GAS import file is formatted.

The assay batch name is assumed to be the same as the Geosoft database file name.

This import creates a mask channel and sets the values to "1". The name of the mask channel is taken first from the Geochemistry Preferences, and if that value is not defined, then defaults to "ChemMask".
