The Image Correction screen has been updated as of . This is being discussed with Lab Working Group. The new interface allows the user to calibrate (image correct) with other colors on the Xrite color checker and provides a visual display of the colors calculated by the RGB values of the Xrite color checker and the corrected color. For now, continue to select the white, shades of greys and black for image correction calibrations.

- 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.
- Decimate Interval: The interval that sets the recorded offset along the length of the core. This value can be set between 1 - 2.9 cm
- 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.

By default the instrument is set for imaging the archive half and will not allow you to scan a working label. If you want to take a picture of a working half you need to go to the MANUAL tab and select W (working) into the Section Half label (Figure 4849). Once you have selected W (working), you will not be able to scan an archive half; in order to do that you need to go back into the MANUAL tab and re-select A (archive).

7. The Image Crop window (Figure 4950) pops up. An image should be cropped to include all material and the inner edge of the end-cap. RGB data will exclude data outside of the Crop area. The green box is the IMS estimation of the crop area. Click and drag the green lines to adjust the cropped area at the top, bottom, and sides of the image. Tools in this window include:

In MUT the 'active analyses' (Figure 5556) should be set to Linescan Image, Processed RGB channels, and Whole-round Linescan. Linescan Image and Processed RGB Channels are for section half measurements. The Whole-Round Linescan Image is for 360 Imaging of hard rock cores. All three analyses should be set in the 'Active Uploaders' Column. Note it is ok for analyses to be in the 'Active Uploaders' even if MUT at that instrument host does not generate those files.

Hi RES RGB: This file default is turned off and can be turned on in Instruments > Camera: General Setup (Figure 357). The Hi-Res RGB file reports a Red, Green, and Blue value for each line of pixels down the length of the core. 1cm is 200 lines of pixels so a 150cm core will yield approximately 30,000 lines of data depending on the exact crop length. The file is not currently uploaded to the database and is instead copied to data1 at the end of the expedition. The files can be put on the server for scientist access to a convenient, shared location such as UserVol.
VCD-S: The SHIL can preserve a digital copy of the VCD-S that is printed out. If a scientist wants to keep a digital copy of the scratch sheet turn on the feature in Instruments > Camera: VCDS Setup (Figure 5657) . Files are then written to C: data > in > VCD-S. These files are not uploaded to LIMS and should be put in data1 at the end of the expedition. The files can be put on the server for scientist access to a convenient, shared location such as Uservol.

The track's push system consists of a NSK linear actuator driven by Schneider Electric stepping motor: MDrive23. The MDrive 23 is a high torque 1.8º integrated motor-driver-controller that connects to the PC via USB-RS485 cable. An IODP-built interface board (Figure 5758) provides power control, emergency, limit/home switches, specialty I/O connections, and status lights. With the exception of a built in "Home" function, the MDive's IMS motion software module provides direct control of the motor's functions. The motor can be installed directly out of the box without any special preparation.
...
Note: If the motor fails to initialize or locate the home switch, then an error will be reported. At this point, access the motion control utilities for trouble shooting. The START button will not appear and measurements are prevented.

Click Motion Profiles to open Motion Profiles window (Figure 6364). The profiles are used to set the speed and acceleration profiles used by the track.
Setting the correct values for the motion profile takes a little experimentation to make the track run efficiently and safely.
Figure 6364. Motion Profile window.
DAQ Move: This profile controls moves between measurement positions. Set this to a reasonable speed with gradual acceleration so the pusher does not bump the sections.
Limit Seek: This profile finds the limit switch locations. Do not exceed 5 cm/sec and use a large deceleration value or the core could overrun the limit switch and hit the mechanical stop.
Home Final: This profile finds the final location of the home switch. Do not exceed 1 cm/sec and use a large deceleration value.
Load/Unload: This profile moves the pusher back to the load position. Set this to a reasonable but high speed with gradual acceleration and deceleration values. Setting this too slow will waste time, but keep safety in mind.
Push-Slow: This profile allows the pusher to move the new section into contact with the previous section and to locate the top of section. Use a speed a little less than the DAQ Move speed with slightly lower acceleration and deceleration values.
Push-Fast: This profile allows the pusher to move quickly to the TOS switch. Typically, it is set the same as the Load/Unload values.
User Define: This profile is used for testing only in the Motion Utilities program.
