Analyze ECGs is a graphical data analysis tool for use on analog input DAQ data, such as that of RTLab. It is useful for opening the '.nds' file format produced by RTLab's data acquisition program, DAQSystem (it can also open regular ASCII files). Aside from being a general-purpose multichannel analog data editing tool, it also contains custom features useful for analyzing cardiac data. However, it can be used for editing/viewing general-purpose data as well. Additionally, this program can convert '.nds' files to ASCII format data.
Asymptopia Flashcard System uses Motif and LaTeX to produce, manage, and use attractively formatted flashcards. You load some or all of your "collections" and set the timer for pop-up frequency. The GUI interface and "Collection Manager" make creating and modifying flashcards as simple as pushing a single button. A knowledge of LaTeX is only required when entering special symbols.
