Error during index built

[desmodus1984]

Hi,
I am interested in doing genome annotation, and Braker3 mentions Hisat2 to map RNA reads to a genome assembly.
I installed Hisat2 in conda, and then I used the following script to make the index for the genome:
hisat2-build -p 64 -f HydLep.fx.fasta HydLep
Using 64 cores is too much?
I was expecting it to run fast, and when I checked the error/log of the job in PBS,
The log looks okay-ish:
Sorting block time: 00:00:12

But the error mentions an issue:

Since I was expecting it to finish fast, I added a loop to start mapping the RNA data to the genome,

for i in /data/common/juanpablo.aguilar/analysis/RNA/*_1_trim.fastq;
        do
        base=$(basename $i "_1_trim.fastq")

hisat2 --phred33 --dta -x HydLep -S ${base}.sam \
        -1 /data/common/juanpablo.aguilar/analysis/RNA/${base}_1_trim.fastq -2 /data/common/juanpablo.aguilar/analysis/RNA/${base}_2_trim.fastq \

samtools view -b -h -q 20 -F 4 ${base}.sam > ${base}.bam

but I am not sure that the index creating worked well. I was expecting a clear, explicit, message that the index was done, and/or that the loop failed.

Could you tell me how to find if the index was properly created?

Thank you.
