ERROR : Unknown image format/type

[DOH-KEW4303]

I am stuck trying to troubleshoot this error when I run 'clockwork' command. I downloaded the version clockwork_v0.11.3.img and have made it executable with chmod. I have singularity version 2.4.2-dist installed. Any help is appreciated!

I have also tried
singularity build clockwork_v0.11.3.img

and error is:
ERROR: clockwork_v0.11.3.img is not an image file

I would use a newer version of singularity - 2.4.2 is very old. The clockwork images on github were built using version 3.5.3.

What happens if you run this?

singularity exec clockwork_v0.11.3.img clockwork

[DOH-KEW4303]

Ah I see. It's the version that installed when I ran conda install singularity

From the command above I get:
ERROR : Image path doesn't exists
ABORT : Retval = 255

[martinghunt]

That error is suggesting that the file clockwork_v0.11.3.img doesn't exist. Can you check that it does?

I doubt that singularity 2.4.2 will work on new images. It looks like it's from Dec 2017 and is a major version too old.
