MACS2: Too few paired peaks (0) so I can not build the model!

Description of the bug

Hello,

While running the pipeline, it is encountering issues when running MACS2. Here are the specifics:

-[nf-core/chipseq] Pipeline completed with errors-
ERROR ~ Error executing process > 'NFCORE_CHIPSEQ:CHIPSEQ:MACS2_CALLPEAK (WT_HRCA_IP_REP1)'

Caused by:
Process NFCORE_CHIPSEQ:CHIPSEQ:MACS2_CALLPEAK (WT_HRCA_IP_REP1) terminated with an error exit status (1)

Command executed:

Command error:

ARGUMENTS LIST:

name = WT_HRCA_IP_REP1

format = BAM

ChIP-seq file = ['WT_HRCA_IP_REP1.mLb.clN.sorted.bam']

control file = ['WT_INPUT_REP1.mLb.clN.sorted.bam']

effective genome size = 1.00e+06

band width = 300

model fold = [5, 50]

qvalue cutoff for narrow/strong regions = 5.00e-02

qvalue cutoff for broad/weak regions = 1.00e-01

The maximum gap between significant sites is assigned as the read length/tag size.

The minimum length of peaks is assigned as the predicted fragment length "d".

Larger dataset will be scaled towards smaller dataset.

Range for calculating regional lambda is: 1000 bps and 10000 bps

Broad region calling is on

Paired-End mode is off

I believe this might be an issue because I am using a bacterial genome and other users on the MACS2 GitHub have reported similar problems (macs3-project/MACS#390).

I was wondering what is the best way to resolve this issue? Thanks!
