  • MacP12: a protein property multi-profile plot program for the Apple Macintosh.
    Computer applications in the biosciences : CABIOS, 1993
    Co-Authors: Angela Lüttke, Rainer Fuchs
    Abstract:

    MacP12, a program for the Apple Macintosh, allows simultaneous plotting of two protein property profiles selectable from 12 built-in amino acid property scales. Various parameters such as the region to be analyzed, the size of the sliding window, the weighting function and the size of the graphical output can be easily adjusted by the user, which makes this program appropriate for diverse research questions. Since built-in scales can be simply exchanged, MacP 12 is adaptable to the specific needs of the individual user

  • MacT: Apple Macintosh programs for constructing phylogenetic trees.
    Computer applications in the biosciences : CABIOS, 1992
    Co-Authors: Angela Lüttke, Rainer Fuchs
    Abstract:

    MacT is a set of programs for the Apple Macintosh to construct and evaluate unrooted trees derived from amino acid sequences using a distance matrix method. Programs are designed on a 'one program--one task' basis for (i) determining the branching order in trees consisting of four or five species and calculating various statistical measures, (ii) calculating statistical measures for all possible topologies of unrooted trees and (iii) generating and evaluating trees derived from bootstrapped samples. With four auxiliary programs unrooted trees can be built for maximal 26 species, and the robustness of topologies be tested by bootstrapping.

  • MacPattern: protein pattern searching on the Apple Macintosh.
    Computer applications in the biosciences : CABIOS, 1991
    Co-Authors: Rainer Fuchs
    Abstract:

    A program is described for rapid detection of protein sequence patterns on the Apple Macintosh which makes full use of the information contained in the PROSITE protein pattern database

  • Neurobase: a general-purpose program for acquisition, storage and digital processing of transient signals using the Apple Macintosh II computer
    Journal of neuroscience methods, 1991
    Co-Authors: Peter K. Stys
    Abstract:

    A general-purpose system for the acquisition, storage and digital processing of signals is described. The hardware is based on an Apple Macintosh II microcomputer, interfaced to a digitizing oscilloscope and a variety of other laboratory instruments with the aid of A/D, D/A, digital I/O and timer functions on a plug-in card. The software (NeuroBase), written using Apple's HyperCard and compiled Pascal procedures, functions as a programmable waveform database, with emphasis on ease-of-use, expandability, and the ability to customize functions according to the application at hand. NeuroBase is suitable for a wide variety of applications such as studying action potentials from nerves or single neurons, clinical EMG or evoked potential studies, patch clamp data, etc. Full compatibility is maintained with commercial programs so that all data can be exported for more specialized analysis, generation of written reports, or the creation of publication-quality graphics.

  • Response time accuracy in Apple Macintosh computers
    Behavior Research Methods, 2011
    Co-Authors: Ian Neath, Avery Earle, Darcy Hallett, Aimée M. Surprenant
    Abstract:

    The accuracy and variability of response times (RTs) collected on stock Apple Macintosh computers using USB keyboards was assessed. A photodiode detected a change in the screen’s luminosity and triggered a solenoid that pressed a key on the keyboard. The RTs collected in this way were reliable, but could be as much as 100 ms too long. The standard deviation of the measured RTs varied between 2.5 and 10 ms, and the distributions approximated a normal distribution. Surprisingly, two recent Apple-branded USB keyboards differed in their accuracy by as much as 20 ms. The most accurate RTs were collected when an external CRT was used to display the stimuli and Psychtoolbox was able to synchronize presentation with the screen refresh. We conclude that RTs collected on stock iMacs can detect a difference as small as 5–10 ms under realistic conditions, and this dictates which types of research should or should not use these systems.
