Users can adjust three RGB parameters: decimate interval, stripe width, and whether to use the mean or midpoint RGB value. For more information regarding how RGB data is calculated please see Appendix A: RGB Calculation

• Decimate Interval: The interval that sets the recorded offset along the length of the core. This value can be set between 1 - 2.

  9cm

  9 cm

• Stripe Width: Centered in the middle of the core, this determines the width across the core that will be used to calculate RGB data. This is typically set to 2cm. While the value can be changed higher or lower it is commonly at 2 cm. The advantage is this width provides enough material to not exaggerate small disturbances but rather provides RGB data representative of the bulk lithology.
• Mean or Midpoint: Can choose how RGB is calculated for the interval. Interval mean calculates the mean RGB values over the interval. Interval Midpoint uses the RGB value at the center of the interval. This is typically set to Interval Mean.

Adjust RGB Settings

1. Go to Instruments > General Setup

Camera Speed

Camera Speed is calculated during the calibration procedure. The camera speed set must be lower than the speed determined by the calibration or else the camera will start 'dropping lines'. Dropped lines means the camera is moving too quickly to calculate the RGB and offsets at the bottom of the core will return values of '0'.

To adjust the camera speed go to DAQ > Image Capture Setup

Start A Measurement

1. Adjust values in the 'RGB Data' setting controls. The 'General' and 'Dropped Lines Warning Threshold' should not need to be adjusted. If something needs to be altered talk to the programmers and ALOs.
2. Click 'Accept' to save values. If select 'Cancel' the values will revert back to prior settings and the window will close.

   The area on the left has four fields to define the condition of the sample measurement:
   1. Image Type: 'Section Imaging' or '360 Imaging'. For instructions on the 360 imaging refer to XXXXXX
   2. Wet/Dry: Indicates the type of the material being imaged
   3. Condition: 'Pristine' or 'Sampled/Altered'. Sampled/altered could include imaging the working half or a highly disturbed section. Most instances should be pristine.
   4. 360 Imaging: This area is grayed out unless '360 Imaging' Image Type is selected. For instructions on the 360 imaging refer to XXXXXX

         The Image crop restricts users to limit adjustments to 2cm or less. The message box will indicate if the crop has exceeded allowable limits and the 'WRND Info' message box indicates if and where any whole round samples were taken from the section. If the image needs to cropped by more than 2cm check the correct section/end cap is being uses, a styrofoam spacer is not missing, and the curated length. Cores can expand so if the curated length is incorrect, talk to    to the curator on shift to correct the length. Note this will also create a need for the curator to re-calcuate depth of the hole. If the error is in the curated length of the core a user can check the 'override crop restriction' button to crop the image and upload the data.

Uploading data

...

Data Structure

Two files are uploaded to LORE via MegaUploadaTron (MUT). Both files must be present or no file will not upload:

1. .roi file
2. .RGB file

.roi File: Contains callouts to the uncropped TIFF , uncropped JPEG, and cropped JPEg images. The images are linked files in LORE as Images > Core Closeup (LSIMG).

.RGB File: Contains the red, green, and blue values calculated for each offset. The information is in LORE under Physical Properties > RGB Channels (RGB).

The files are independent of eachother, both do not need to be present in order to upload, and often appear in MUT at different times.

MUT and .ini file

Be aware uploaded files have a callout for the .ini file. There is only one .ini file and the files will callout the .ini file currently present at the moment of uploading to LORE. If changes are made to settings that will alter the .ini and there are files piled up that have not uploaded to LORE, those files will upload the current .ini file, not the .ini file settings used for measurement. This implies files could have incorrect .ini files if rapid changes are made and users are not being careful.

How to Upload data

1. Open up MUT (FIG XX). Use LIMS Applications password to login.
2. Set 'Project' at the bottom of the screen to either the current expedition or '999' if performing tests.
3. Files with checkmarks in the right column will upload. A green arrow in the COLUMN XX indicates it is in process of upload. A purple question mark indicates the file is not recognized by MUT. This could be due to an incorrect sample name or only one file being in the 'IN' Folder.
4. Check 'Automatic Upload'. At the refresh interval the files will upload to LORE.
5. After files are successfully uploaded they move from 'data > in' to the 'data > archive' folder. When the files move they will not longer appear MUT. If a file was unable to upload it will move from 'data > in' to 'data > error' and two new buttons will appear in MUT saying 'Show Error' and 'Show Error Files'.

"Scratch sheets" are printouts of section half images produced by SHIL. The sheet is a LabVIEW VI with embedded images that can print automatically when a user 'saves' an image. The VI is scaled to print SHIL images correctly on 11x17" paper in portrait orientation. The scratch sheet can be customized to include various columns to capture descriptions or drawings on paper. The goal of this guide is to instruct how to use and customize scratch sheets.

Data Structure

Each scratch sheet template is it's own VI. Each VI has to have the same root name "VCDS_SHLF". You may add any additional naming after this root name as long as the root remains unmodified.
