About Coder X

CoderX is a software application that is part of the Observational Data Processing System (ODP). It was developed and is currently being maintained by OSLC. CoderX, currently at version 11, allows observations viewed using VHS-VITC, DVD mediums, and/or ASF (Web streaming video) formats to be entered electronically into PCs running Windows XP or better.

CoderX allows you to work with observational data. You can create new types of coding schemas, record observations sequentially via several methods and mediums, find and correct errors in the observations, manage and transform your data, and calculate the reliability of observers.

CoderX has a “minimal” security feature (username/password) that determines if a person should be allowed to use the program, which features of the program should be available to the user, and which files the user should be able to work with. The information is used to help with Observational Data Management.

Limited User Support CoderX has proven to be a helpful tool for researchers here at OSLC; we encourage you to download it. However, it is a system that takes time to learn and implement. It is flexible to allow you to create a brand new coding schema, but defining the new code can prove time consuming in order to get the desired results. If you have an existing coding system, you might have to adapt it to work with CoderX. Your existing data files might have to be reformatted in order to run through the program but in doing so you could use CoderX Reliability options and any of ODP’s transformation and analytical tools. Because of staffing limitations, we can only provide very limited user support.

While CoderX includes extensive on-line help, you might come up with some problem that we were not able to foresee based on our own particular experiences. We will try to anticipate as many queries as possible with a Frequently Asked Questions (FAQ) option and later perhaps run a newsletter from our server. We would also encourage you to visit the references option in order to become more knowledgeable about observational coding. All said, we hope that CoderX can help you with your observational coding projects.

  3. We will only keep the newest version of the program for downloading; meaning older versions are not available after they are replaced with another version. Should you for any reason prefer to run an older version, make sure to create a backup of the version you like.

System Requirements

CoderX runs under Windows XP or better. Depending on the media that you wish to observe, i.e., VHS-VITC, DVD, and/or ASF (Streaming Videos from Media Servers), additional hardware/software might be necessary. CoderX main use is intended for large size coding labs, with several coding stations. Preferably, all coding stations are linked to a network, as it makes data management much more manageable.

Instructions for Installing CoderX

These instructions are also included in the read_me.1st file included with the download.

  1. Use WINZIP to decompress CoderX.ZIP.
    You should now have 7 more files besides
  2. Copy the following files onto disk1: _instpgm.exe, _instpgm.ini, setup.exe
  3. Copy the following files onto disk2: main.mva, data.mva, source.mva
  4. In order to install CODER, choose RUN from the START menu, browse for CODER’s setup.exe, and hit ok.
  5. Follow the instructions on the screen.
    Click here to download the program.
  6. After you have downloaded and extracted the files, and have run the Setup Program, you will want to “extract” the files (click here) to overwrite the existing Coder files.
