This version remains a favorite in the field because it is free and integrates directly into Microsoft Excel, allowing for a seamless transition from raw data to professional charts. Key Features of the v9.1 Update

While original versions were tailored for older Excel environments, the latest iterations ensure compatibility with current systems:

Comprehensive Statistics: Calculates mean, mode, sorting, skewness, and kurtosis using both the Folk and Ward (1957) graphical methods and moment methods.

Multiple Input Support: Processes data from standard sieving, laser granulometry, X-ray sedigraphs, or Coulter counters.

Textural Classification: Automatically assigns samples to one of 15 textural groups defined by gravel, sand, and mud percentages.

High Efficiency: Capable of processing approximately 50 samples per hour, providing both tabular summaries and graphical outputs like frequency histograms. How to Use GRADISTAT for Your Research

Data Entry: Use the "Multiple Sample Data Input" sheet to enter sieve apertures or laser bins. Apertures can be in ascending or descending order.

Sample Info: Input your weights or percentages. The program supports up to 230 rows of data.

Calculation: Click the "Calculate Statistics" button. The program will generate a full summary on the "Multiple Sample Statistics" sheet.

Visuals: Access the "Gravel Sand Mud" and "Sand Silt Clay" sheets for automatically generated triangular diagrams and cumulative distribution plots.

Whether you are studying coastal sediment dynamics or atmospheric dust provenance, GRADISTAT v9.1 remains an essential tool for turning raw measurements into meaningful scientific data.

GRADISTAT is a widely used Microsoft Excel-based program for grain size analysis and statistical calculations in sedimentology and geomorphology. Acquiring GRADISTAT

Official distribution is handled by Kenneth Pye Associates Ltd (KPAL). While older versions (v4 to v8) are commonly available, "v9.1" often refers to internal or specific site-modified versions, as the main public sequence progressed from v8.0 directly toward GRADISTAT-PRO.

Official Downloads: The standard stable versions can be found on the KPAL GRADISTAT Software Page.

Alternative (R-based): For users seeking more modern automation beyond Excel, the G2Sd package on CRAN is an evolution of the GRADISTAT v4.0 macro. Getting Started Guide 1. Data Preparation

Input Types: The program accepts weights from sieving or percentages from laser granulometers.

Format: Open the .xlsm file and navigate to the "Single Sample Data Input" or "Multiple Sample Data Input" sheet.

Aperture Sizes: Enter sieve/bin sizes in column B (either ascending or descending). Ensure they are consistent across all samples in a batch. 2. Entering Sample Information

Fill in the green cells above each sample with the sample identity, analyst name, and date.

Pan/Fine Material: If you have material in a pan (fines), enter its weight at a class size of zero or leave it blank. The program typically assumes these are larger than ) for calculation purposes. 3. Calculating Statistics

Click the "Calculate Statistics" button. The macro may take several minutes if processing a large batch (up to 250 samples). Output Metrics: GRADISTAT will automatically generate: Mean, Mode, and Sorting (Standard Deviation). Skewness and Kurtosis. Folk and Ward (1957) graphical measures. Physical descriptions (e.g., "Very coarse sand"). 4. Visualizing Results

Check the "Multiple Sample Statistics" sheet for a summary of all processed data.

The program generates frequency distribution curves, cumulative plots, and ternary (triangular) diagrams to classify sediment texture. Quick Troubleshooting

Macros Disabled: Since GRADISTAT relies on VBA, ensure you "Enable Content" when Excel opens the file.

Weight Warnings: If the sum of class weights exceeds the "Initial Sample Weight," GRADISTAT will trigger a warning; verify your data entry in column C.

Sieve Intervals: For the most accurate Folk and Ward calculations, use sieve intervals of at least whole phi ( GRADISTAT software - Kenneth Pye Associates Ltd

Would you like to know more about Gradistat v 9.1 or is there something specific you'd like to know?

Because "Gradistat" is not a cloud-based software but rather a protected Excel workbook (typically .xlsm or .xls), there is no public "browser link" to access it directly. It must be downloaded and opened in Microsoft Excel.

Here is a post looking at the details, how to access it, and why it remains a standard in geology and sedimentology.

Method B: Laser Diffraction / Pre-calculated Percentages

If you are importing data from a Laser Particle Sizer (like a Malvern Mastersizer):

  1. GRADISTAT can often read raw output files from these machines.
  2. Look for a menu option in the GRADISTAT toolbar (usually a floating menu or a tab in the Ribbon) labeled "Import Data" or "Read Malvern File."
  3. Select your .txt or .csv output file from the instrument software.

Legal and Ethical Considerations

Is it legal to use the gradistat v 91 link? Since v 9.1 was released as Freeware (not trialware), the original license permitted free distribution for academic and non-commercial purposes. However, because CCAP no longer supports it, using v 9.1 is generally considered "legacy use." You cannot use Gradistat v 9.1 for commercial consulting without purchasing the Pro version.

Method A: Sieve Data (Weight retained)

If you have raw data from sieving (weights in grams):

  1. Locate the Input Sheet (often named "Input" or "Data").
  2. Enter your sample ID in the designated column.
  3. Enter the Weight Retained (g) for each sieve class.
    • Note: Ensure you match your weights to the correct Phi ($\phi$) or Millimeter size columns. The sheet usually lists standard sieves ($-2\phi$, $-1\phi$, $0\phi$, etc.) across the top.

Conclusion: Your Action Plan

If you are a sedimentology student or a researcher stuck because you cannot find the tool, here is what you need to do:

  1. Save this article for the step-by-step installation guide.
  2. Use the archival search methods described in Section 3 (GitHub and University .edu domains) to find a verified gradistat v 91 link.
  3. Apply the VBA Reference fix if you receive compile errors.
