Data transfer: Arina and Velox

This page covers how to get your data off the Spectra computers at Stanford SNSF: Arina 4DSTEM datasets and Velox HAADF .emd images to a USB drive, plus how to mount the lab Mallard network share for remote access. Drafted by Sangjoon Bob Lee from staff notes and images.

Overview

Save Arina 4DSTEM data to USB

• Plug your USB into the Arina PC

  1. Plug your USB drive into the computer below (the TVIPS scan generator PC). The USB port is circled.

     

• Copy your dataset to USB

  1. Open the NOVENA destination folder set during acquisition, find your session’s .h5 and _master.h5 files, and copy them to your USB drive.

Save HAADF images to USB

Velox saves HAADF images and other .emd files locally on the control workstation.

• Plug in the USB drive

  1. Insert your USB drive into the PC. It appears as a new drive in File Explorer.

     

• Find the CaptureData folder and copy

  1. Open the CaptureData (X:) folder. Velox saves your session’s .emd files here, organized by date.

  2. Copy your dated folder to the USB drive.

     

Mount the Mallard network share

For remote access to the lab data server, map the Mallard share as a network drive instead of copying to USB.

• Open Map network drive

  1. In Windows File Explorer, right-click This PC and select Map network drive....

     

• Enter the share path

  1. Set Drive to Z: and Folder to \\mallard.stanford.edu\mallard_arina.

  2. Check Reconnect at sign-in, then click Finish.

  3. Enter the Mallard password when prompted. The password is in the pinned channel of the Colin Ophus group internal Slack.
