GMP2GDAT
GMP (Genome Mate Pro) and GDAT (Genealogical DNA Analysis Tool) can not open or "read" each others databases.
As such, if you want to use your GMP database in GDAT, you will need to convert it first, via the GMP2GDAT conversion program.
To convert your GMP database to GDAT you will first need to start with a brand new GDAT database. Caution - the conversion process overwrites the currently open GDAT database.
You also need to have your GMP database on version 2020r13 for a conversion to work. Databases using earlier versions of GMP are unable to be converted.
Before starting conversion, open your database in Genome Mate Pro.
Find a relative that is also a profile.
Open the record to the Relative Detail > About view.
In the lower right hand corner, ensure that all Source Keys are in bold.
If one or more are not in bold, right click and select "Toggle as Primary Key".
Repeat from step 1 for every profile.
You should now be ready to convert your GMP database to GDAT.
Important: While you should lose nothing in the conversion process, GMP went through so many transitions over the years that it is possible that something will not convert properly. It is important therefore to keep your GMP database for reference.
GMP 2020r13
Provided for conversion to GDAT. No longer supported.
Open GMP2GDAT. You will be prompted to either Open an existing database to continue the conversion process, or to create a new database to start the conversion process.
Clicking on "Open" will allow you to choose from a previously started conversion file, and continue where you left it last time.
Clicking on "New" will open your computers file select window, where you can then choose your new database's name and save it.
The default name for new databases in in the format of "GDAT_created_on_yyyy-mm-dd" - where yyyy-mm-dd is the date of creation.
You may wish to append the name of your new database with something unique, or change the entire name completely. Two databases of the same name can not exist, and you will be warned if this situation arises and you can make a choice accordingly.
The display box now shown will step you through the conversion process with instructions for each step shown at the bottom of the window.
"Press Start to begin" - this will open a file select window, allowing you to navigate to and select the GMP database you wish to convert.
Once the GMP database is loaded, the message will read "Database prepped for conversion. Double click on Step 1." As instructed, double click on Step 1.
If the message at the base of the screen reads "Open database failed", then you will need to ensure that your GMP database has been edited within the 2020r13 version. If you have already done this and are still getting the same message, then you may need to start a fresh GDAT database.
While a conversion step is in progress, the message at the bottom of the window will read "Converting (step) .... please be patient" - where (step) refers to the current step being undertaken.
During conversion steps it can be normal for the program to also display the "(Not Responding)" message in the top of the window. Be patient, it is highly unlikely that the program has actually stalled, it is far more likely to still be working in the background. Be patient, it will finish the step in due time.
At the conclusion of each step, the message at the bottom will read
"(step) conversion complete" - where (step) refers to the step just undertaken. The step just completed will also now be greyed out.
To continue, simply double click on the next step in the list that is still in the black colour.
Note: If you need to pause at any point of the process, you can do so at one of these safe pause points. You may close the GMP2GDAT program at this time, but do not alter anything within your original GMP database during this paused time. When you are ready to resume, load the GMP2GDAT program, and click start. Ensure you select the same database as before, and proceed with the conversion process.
Once the final step has been completed, your display will appear as above.
Close the program. Your new database is now available to use in GDAT.
The time taken for each step will vary from database to database, some examples have been included below to show this, along with the original GMP stats.
Note: The total time take can vary based on a variety of factors, including your drive type, and as such, your total time taken may vary greatly from the examples shown below.

It is evident that if you have a very large GMP database, the conversion process can take many hours. As such, you may choose to do a "partial conversion", and complete in order steps 1 through 4, skip steps 5 and 6, and then complete steps 7 and 8.
You will need to load chromosome and ICW files at the end of the conversion process to complete your new GDAT database.

From a GDAT user: I had 111 profiles in my GMP database, about 638mB file size. I had over 385k relatives, over 778k segments, and over 1.38mill triangulations. The conversion process took me about 157 minutes, a little over 2.5 hours. I did not skip any steps.
