Unhandled exception System.NullReferenceException

[dhaselb]

Hi I was trying warpcraft on my data and somehow dont get it running. This is what I did and what I get:

warpcraft --input run_data.star --particlediameter 300 --angpix 1.16
Executing with the following parameters:
Input model: C:\Users\david.haselbach\Desktop\warpcraft-test\run_data.star
Particle diameter: 300 A
Pixel size: 1,16 A
Iterations: 5
Steps per iteration: 40
Batch size: 300
Threads per GPU: 1

Pre-read particles: True

Output B-factor: 0 A^2
Local resolution window size: 40 px
Local resolution FSC threshold: 0,5

Dilate mask for fine model: 5 px
Body overlap region: 2 px

Init coarse atom model with:
Number of coarse atoms: 5000
Oversample fine atoms by: 4x
Update modes after each iteration: False
Normal modes: 10

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.

Yes, I have had an identical issue. Any help would be very appreciated. Dying to try WarpCraft.

It seems that the required input is not RELION's STAR file. I am using something like below but I hope @dtegunov could provide a sample input.
