If you are looking to advance your project, I can help you with the next steps if you tell me:
Defining whether the data is in mm or φ units.
used globally by geomorphologists, sedimentologists, and environmental scientists to process granular data. Originally written by Simon Blott and published alongside Kenneth Pye in 2001, this Microsoft Excel-integrated VBA package simplifies complex statistical calculations for unconsolidated sediments. If you are looking for the official application, the primary deployment hub and documentation can be reviewed directly via the Kenneth Pye Associates Ltd (KPAL) Software Portal .
The original program (Versions 4.0 through 8.0) was distributed directly via the Kenneth Pye Associates Ltd Official Site . Over time, updated variations like have been adapted by academic communities to maintain compatibility with modern, 64-bit editions of Microsoft Excel and to automate multi-sample workflows. Key Technical Capabilities
: Input your weights or percentages. The program supports up to 230 rows of data. gradistat v 91 link
Because GRADISTAT is proprietary academic software packaged as a macro-enabled .xls or .xlsm workbook, downloading it from untrusted third-party link directories can expose your computer to malicious spreadsheet macros.
: Includes the popular Folk and Ward (1957) graphical methods and the method of moments.
It computes statistics in both metric units (microns/millimetres) and logarithmic φ (phi) units .
: It calculates mean, mode, sorting, and skewness using both arithmetic/geometric (metric units) and logarithmic (phi units) methods. If you are looking to advance your project,
The software automatically calculates the mean, sorting, skewness, and kurtosis.
Launch the file. When prompted by the top warning alert ribbon, click or Enable Macros . 2. Entering Sample Parameters
The official link for GRADISTAT Version 9.1 is available through the K. Pye Associates downloads page
Here is a post looking at the details, how to access it, and why it remains a standard in geology and sedimentology. If you are looking for the official application,
The software calculates logarithmic statistics using the traditional Folk and Ward graphical method. It automatically assigns standard descriptive terms to characterize your sample, providing clarity on: : The average size of the sediment distribution.
To avoid system script blocks and visual execution runtime issues within Microsoft Excel while using the GRADISTAT version 9.1 macro, follow these step-by-step procedures: 1. System Preparation and Macro Security
The software operates within Microsoft Excel, utilizing Visual Basic to calculate parameters using both the Folk and Ward (1957) and moments methods. It is capable of processing data for a wide range of unconsolidated sediments. GRADISTAT v9.1 vs. Previous Versions
