SOFTWARE SURVEY SECTION

Editor's Note: The following Software Descriptions have been submitted by our readers in response to our call for an open exchange of information on software programs. They are offered without review or comment to provide a rapidly published, easily accessible avenue of communication. Other readers with relevant software packages are invited to complete and submit a Software Description Form (found at the end of this section).

Software package NI-OOl-S84 Four programs: AMINOA, PROCHO, QUENCHL, and STD

Contributor: Cynthia Theall, Massachusetts Institute of Technology, E25-617, Cambridge, HA 02139

Brief description: AMINOA: Determines sum of five or six long chain neutral amino aclds for ratio of each neutral amino acid to the others, i .e . , trp/tyr+leu+leu+phe+val+met. Also determines mean and SEM for each group of subjects. Amino acid values are pTasma values obtained from an amino acid analyzer.

PROCHO: For determination of dry diet when ther is a two-choice diet pair. Total grams of Diet A, Diet B, total grams consumed, grams of protein, carbohydrate, fat, % protein, % carbohydrate, % fat, calories, and protein/carbohydrate ratio are calculated. Data input includes decimal values for % pro, carbohydrate and fat in each diet and moisture percent of each diet followed by wet (or raw) weight in grams of Diet A and Diet B.

QUENCHL: Converts CPM to DPM for H3, C]4 , or H3+CI4 (double-labeled samples). Can edit for background changes. Equations in program are derived from quench curves which can also be edited in program.

STD: Determines standard curve for neurochemistry data and gives correlation coefficient. Also determines x values from known y values based on standard curve.

Potential users: Technicians, graduate students.

Fields of interest: Neurochemistry, nutrition, radioisotope work.

§ This application program in the area of neurochemistry (amino and std), nutrition (procho), and radioisotope work (quenchl) has been developed for the Vax II/780 (Digital) in BASIC to run under VMS V3.5. I t is available on 600 bpi magnetic tape; 1600 density in ASCII.

S The minimum hardware configuration required is a Digital VT-IO2 terminal with attachment to a LA50 printer. No user training is required. There is minimal documentation. Source code is available.

S The package is f u l l y operat ional . I t has been in use at 1 s i te since November 1983. The cont r ibu tor is avai lable fo r user inqu i r ies .
