GEMS TDB Technical Information | Mac OS | "/Applications/Gems3.app/Contents/" |
| Linux | "~/Gems3-app/" |
| Windows | "C:\Selektor\Gems3-app\" |
Each file in GEMS database format, e.g. phase.supcrt.inorg.ver1998.pdb, comes with an (automatically created) index part, e.g. phase.supcrt.inorg.ver1998.ndx. This index file is used by the program to speed-up reading of database files and linking them into the database chains. For brevity, the *.ndx files are not shown in the lists below.
Important:
If you used the GEM-Selektor before the release of version 3.2
(30.04.2013) then we recommend installing GEM-Selektor version 3.2 in a
different folder in order to avoid mixing of files belonging to the
"new" TDB and "old" TDB in the "/DB.default" folder. Alternatively,
first rename the "gems3-app" folder in the location where GEMS3 was
installed into "gems3-app-old"; then re-install GEM-Selektor to the
usual location. For Mac users: simply remove the "gems3.app" from
"/Applications" and put there the new "gems3.app" from the version 3.2
dmg installer.
1. PSI/Nagra part of GEMS default database is located in files:
In the GEMS version of the PSI/Nagra TDB 12/07, the core data and the recommended application data are taken together (they are referred to as recommended data) and are separated from the supplemental data in such a way that new modeling projects can be made with recommended data only, or with a combination of recommended and supplemental data. There is no use in calculations with the supplemental data only. The following database files concerning the PSI/Nagra TDB 12/07 are contained in the /DB.default folder:
| sdref.psi-nagra.rec.refs.ver12-07.v0.1.pdb | bibliographic references (SDref records) |
| icomp.psi-nagra.rec.elements.ver12-07.v0.1.pdb | elements (IComp records) |
| dcomp.psi-nagra.rec.solids.ver12-07.v0.1.pdb | recommended solids (DComp records) |
| reacdc.psi-nagra.rec.solids.ver12-07.v0.1.pdb | recommended solids (ReacDC records) |
| dcomp.psi-nagra.rec.gases.ver12-07.v0.1.pdb | recommended gases (DComp records) |
| reacdc.psi-nagra.rec.gases.ver12-07.v0.1.pdb | recommended gases (ReacDC records) |
| dcomp.psi-nagra.rec.aqueous.ver12-07.v0.1.pdb | recommended aqueous species (DComp records) |
| reacdc.psi-nagra.rec.aqueous.ver12-07.v0.1.pdb | recommended aqueous species (ReacDC records) |
| phase.psi-nagra.rec.phases.ver12-07.v0.1.pdb | recommended phases (Phase records) |
| compos.psi-nagra.pco.generic.ver12-07.pdb | predefined composition objects (Compos records) |
| reacdc.psi-nagra.sup.solids.ver12-07.v0.1.pdb | supplemental solids (ReacDC records) |
| reacdc.psi-nagra.sup.aqueous.ver12-07.v0.1.pdb | supplemental aqueous species (ReacDCC records) |
| phase.psi-nagra.sup.phases.ver12-07.v0.1.pdb | supplemental phases (Phase records) |
As discussed here, the PSI/Nagra TDB 12/07 can also be used together with the SUPCRT92 part of the default database.
2. SUPCRT92 part of the default database (imported) is located in files:
| icomp.supcrt.ver1998.pdb | elements (IComp records) |
| sdref.supcrt.refs.ver1998.pdb | bibliographic references (SDref records) |
| dcomp.supcrt.organic.ver1998.pdb | organic aqueous species and gases (DComp records) |
| phase.supcrt.inorg.ver1998.pdb | phases (Phase records) |
| dcomp.supcrt.inorg.solids.ver1998.pdb |
inorganic solids (DComp records) |
| dcomp.supcrt.inorg.gases.ver1998.pdb | inorganic gases (DComp records) |
| dcomp.supcrt.inorg.aqueous.ver1998.pdb | inorganic aqueous species (DComp records) |
| compos.supcrt.pco.inorg.ver1998.pdb | predefined composition objects (Compos records) |
The SUPCRT92 part of the default database can be used either alone or combined with the PSI/Nagra TDB 12/07.
3.
Supporting database files
| sdref.support.template.scripts.ver3.0.pdb | collection of templates for print/export, import and math scripts (SDref records) |
This default script library consits of a collection of SDref records that contain print/export, import,
and template math scripts that should help
users to perform data import/export operations and to write
math scripts. This default script library is located in the sdref.template.scripts.*
files in the /program/DB.default directory. The files can be manually linked to any user-created modelling
project to make the script libraries accessible within the project database.
GEM-Selektor version 3.1 and lower:
These installers contain the Nagra-PSI 01/01 dataset as default
(kernel) TDB, now superceded with the PSI/Nagra 12/07 dataset (see
above). These files are listed below for compatibility with earlier
releases of GEMS.
Each GEMS database file,
e.g.
rtparm.nagra-psi.pdb,
comes with an (automatically
created)
index counterpart, e.g. rtparm.nagra-psi.ndx.
This index file is used by the
program
to speed-up reading of database files and linking them into database
chains.
For brevity, the *.ndx
files are not shown in the lists
below.
"Kernel"
part
of the GEMS default database is located in files:
icomp.kernel.nagra_psi.pdb
compos.kernel.nagra-psi.pdb
dcomp.kernel.nagra_psi.gases.pdbdcomp.kernel.nagra_psi.ions.pdb
dcomp.kernel.nagra_psi.prods.pdb
dcomp.kernel.nagra_psi.secms.pdb
dcomp.kernel.nagra_psi.solids.pdb
reacdc.kernel.nagra_psi.prods.pdb
reacdc.kernel.nagra_psi.solids.pdb
phase.kernel.nagra-psi.pdb
phase.kernel.nagra-psi.solutions.pdb (under construction)
The following files are not used when records are copied into a new project directory:
rtparm.nagra-psi.pdb (Examples of T,P corrections - under construction)
"Complementary" part of the default database (imported SUPCRT data) is located in files:
icomp.complem.slop98.pdb
compos.complem.slop98.pdb
dcomp.complem.slop98.aq-inorg.pdbdcomp.complem.slop98.gases.pdb
dcomp.complem.slop98.solids.pdb
phase.complem.slop98.pdb
dcomp.complem.supplem.slop98.organic.pdb
sdref.complem.pdb (Bibliographic references to complementary data base)Last updated: 30. 04. 2013
