when specifying a conda environment and sge executor, I get an error :

cat work/a6/c9eea2ea1f3a5725e3b9a6c0b2e548/.command.log

/opt/sge/default/spool/execd/node161/job_scripts/1749279: line 68: activate: No such file or directory

the conda env works when using local executor. Any ideas what might be going on? If I qlogin to a compute node, source activate <env> works.

Hi, I was trying to loop between processes but it is impossible with nextflow, isn't it ?
It must be a DAG

No, you can do it

hey guys!
In my hands it seems that when I resume a pipeline I can not modify the number of queues I want to use (process.queueSize) editing the nextflow.config:

manifest {
    mainScript = ''

profiles {
    standard {
    process.executor = 'local'

    cluster {
    process.executor = 'slurm'
        process.queueSize = 1
        process.cpus = 5
        process.memory = '1 GB'        


As you see I want to reduce the queueSizeto be 1. The reason is that I just want to run a test without occupying additional nodes in the cluser. Am I doing something wrong or is this behavior expected?

I think that queueSize in on the executor scope

@tbugfinder Concerning my segfaults in Salmon quant, no changing image, instance and increasing memory did not help

which base image are you using? the same container is working locally? likely this is a salmon problem.
