issue spades: Expected assembly files were not found in output.

[haxacloruro]

Hi, I used spades to assembly my data and I successfully did it in all my samples, but not in five. I'm having a warning that says "Expected assembly files were not found in output". At the end I have empty contig files from those samples. I do not understand why in this group of samples Spades is working for some samples but not for all. I wonder if you could have an idea what is happening. Best!

I am having the same issue. Have you figure this out already?

[haxacloruro]

no yet...

[brantfaircloth]

It is very likely that Spades is running out of RAM to assemble the reads you have for the samples that are not assembling. There are two potential ways to fix this issue:

1. Find a machine with sufficient RAM and set the --memory parameter to ~ 4 GB below the amount of RAM on this machine, e.g. --memory 60. Or even better, --memory 250. The value you use is the number, in GB, of RAM to allocate to Spades.

2. Alternatively, you can downsample the reads you have for the individuals that are failing to assemble, using an approach like this. I usually downsample to something between 3 million reads (in total; so 1.5 million in R1 and 1.5 million in R2) and 6 million reads.

I had not not clarify the allowed memory paramter. It worked after I did. Thank you.
