MacSECPROT: two programs in BASIC to evaluate protein secondary structure.

Two interactive programs in BASIC are described, which provide useful tools to evaluate protein secondary structure. Output is given in two formats: (1) graphics are displayed on screen, which can be printed immediately, and (2) textfiles are saved to disk as permanent records and can be printed with a word-processing program. The programs are fast and easy to use and could be a valuable teaching aid in biochemical and molecular biology courses. Program lists are written in Microsoft BASIC for the Apple Macintosh, but can be adapted to other machines accepting graphic commands.

REPLI: a program in BASIC for determination of approximate sample size.

REPLI, a program written in elementary BASIC, calculates the approximate sample size, which is required to detect a desired difference between any two group means in an experiment with n groups for a given probability and at three significance levels of the means difference. A prior knowledge of the variability of data in the groups is expected in order to base the estimate on a rational footing. If this knowledge does not exist, an educated guess and/or several trials with different assumptions on the most likely variability can be used. The a priori estimate prevents that sample sizes are completely out of a reasonable range. Since the program is applicable for experimental settings where several groups need be investigated, it is particularly interesting to users of ANOVA and/or comparable non-parametric tests.
