This section describes the folders and files types created by Ponemah v6.x during Installation and Acquisition.
Main Data Folder
The default installation of Ponemah creates a folder that all data will be collected in. The default location and name of this folder is on the root drive with a name of Ponemah_Data.
The user has the ability to change both the location of the folder and the name of the folder after the application is started.
When a user creates a new Experiment, a new folder is created in the data folder that will contain all of the needed files for that Experiment and each file created in this folder will have the base name of the Experiment in the filename.
Ponemah will default the new Experiment name to Experiment_nnn where nnn is a numeric value of that particular Experiment name. The user can choose to change this name before the Experiment is created.
Once an Experiment has been created and an acquisition is started, Ponemah will create a set of files with a specific filename structure. Depending on the contents of the file, the extension of that file will designate its usage.
Each file created for the Experiment will have as the first part of the filename the Experiment name itself. For example, with an Experiment name of RatCardioStudy, then all of the Experiment files will be in the form of
Filename Extension Meanings
The following table list the definitions for the files that are created.
This is a SQLite database that contains all the needed information for the Experiment setup.
This replaced Ponemah’s protocol file (.PRO).
This is a SQLite database that contains the complete Experimental log.
The log contains all information that defines the Experiment such as analysis settings, subject setup and hardware configuration. The log also contains any hardware errors that are generated during the acquisition of data that can impact data.
This is a SQLite database that is generated per subject and contains all of the analysis validation marks, event and user notes, bad data marks for each input.
The database can be updated with new marks during a Review session over the range of data that is loaded.
This is a binary file that contains all of the signal data for a particular subject. There can be multiple files generated for a subject.
A new file is generated every time the subject starts a new sampling collection or when it reaches a predefined size that is user settable in the application or when a predefined time is reached that is user settable in the application.
This is a SQLite database that is generated per subject and contains all of the parameter values, data reduction values and variability results.
The database can be updated with new values during a Review session over the range of data that is loaded.
For Waveform files and Results files, there will also be a file created per subject. If an Experiment has four subjects then the four initial waveform files will be created and four result files would be created.
The waveform files will also have a date and time component associated with the filename.
For the results:
- RatCardioStudy_Rat1.PnmResults where Rat1 is the Subject designation
Many of the files are generated as SQLite files and can be viewed with simple SQLite browser. This browser is included on the release CD and is installed along with the application and is accessible in the Ponemah runtime folder in the Utils folder. Below is the browser that is released with Ponemah 6.10.
Note: Depending on the version of the SQLite browser, the images in this document may be different than what is shown when running the browser.
