Manual calibration procedure
To run the manual calibration procedure, you need to have detector at least configured once (Firmware/ASIC configuration). You may want to always run this command to set these values to default.
Firmware/ASIC configuration: Open the Rogue interface, and In the InitASIC list, type [34,1,1,1,1] and hit enter. This will not configure the Silabs PLL to a , and use the default configuration with clock of 168Mhz and configure all ASICs with default.
...
At this point all ASICs should be generating images (unlocked lanes are disabled). You . Just enable the DataReceiver of each of the ASICs by setting the RxEnable to True, and you can test by hitting the Trigger execute button in root.Trigger. See below.
Set RxEnable to True

Hit Trigger button.
You should see some prints in the terminal for each of the 4 ASICs (dataReceivers).
Now Now you need to go to root.App.TestManualSERDESEyeTraining and open that tab. You will see three configuration parameters. The defaults will Tune for all ASICs. There is still a bug that causes a segmentation fault with setting ASIC to -1. so let's stick with 0 to 3 for now. Again you can start and stop as you wish. See below

...
Tap is the number of data points, and 512 may take a long time, so you can change that to 64. Set the ASIC that you wish to scan, and set the tap number (64 is reasonable), and Keep time per sweep as default (40).
Important note: This function generates some files in the <scripts> folder (namely all_errorsX.csv, delay_spaceX.csv, run_resultsX.csv, and delay_spaceX.csv where X is 0 to 3). If these files already exist, the software will crash. So you need to delete these files, then run the script.

Once your settings are correct, hit the start button, and wait till Progress reaches 1.00 and Message says Done.
Upon a successful finish, this should generate an all_errorsX.csv file where X is 0-3 in the same folder where you ran the software (software/scripts). Navigate to that folder, and run the following script to see the error scan plots.

# run drawEyes.py script for ASIC3 and number of taps set to 64

How to interpret the error scan
The Y axes is error, and the X axis is the number of taps normalized to 1024 (10 bit delay register). If at any point the Y axes is 0, then you have a zero error point for that specific delay value (X).
Example: In the image above, Lanes 16, 22, and 23 seem dead.
AFter documenting, delete the file ((namely all_errorsX.csv, delay_spaceX.csv, run_resultsX.csv, and delay_spaceX.csv where X is 0 to 3)) using the following command:
