Fail to delete temporary folder

Question

[prabin.dm]

I am trying to map reads with rsem-calculate-expression using STAR aligner using a loop, however I am getting an error of the STARtemp folder not being deleted after the first run, hence it is stopping the next run. What wrong I am doing ?

1. I have changed the permission in ..\test_results folder
2. I am running on the same number of nodes as the threads requested.

this is my code

for prefix in $(ls *.fastq.gz | rev | cut -c 12-| rev | uniq)
do
rsem-calculate-expression --star \
                        --star-path /share/pkg/star/2.7.0e/bin \
                        --star-gzipped-read-file \
                        -p 4 \
                        --paired-end \
                        "${prefix}R1.fastq.gz" "${prefix}R2.fastq.gz" \
                        ../genome_indices/rsem-star/rsem-star \
                        ../test_results2/"${prefix}res"
done

This is the error part of the output

EXITING because of fatal ERROR: could not make temporary directory: ../test_results/G20P1sc-C08-res.temp/G20P1sc-C08-res_STARtmp/
SOLUTION: (i) please check the path and writing permissions 
 (ii) if you specified --outTmpDir, and this directory exists - please remove it before running STAR

Answer 1

I found out that the . nfs000000047fe2b1c700000f07 type files are the problem.

Once I directed the output to a new folder, it solved the issue :)
