I am trying to use amplican to evaluate nanopore sequencing fastq file of CRISPR'd region. I only have one fastq file for the sample.

I have made the config csv file. However, when running the amplicanPipeline function I get an error that my forward file is blank, but my forward file column contains the name of my fastq file. See screenshot of my config csv below.

# path to example config file
config <-  "~/Desktop/pvol2/Rat_nanopore/try/config_summary_2.csv"
fastq_folder <-"~/Desktop/pvol2/Rat_nanopore/try/W4FBKV_1_678.fastq"  
# output folder, a full path
results_folder <- "~/Desktop/pvol2/Rat_nanopore/try"  
#  run amplican
amplicanPipeline(config,fastq_folder = fastq_folder, results_folder=results_folder,fastqfiles = 1)

Checking configuration file...
Error in amplicanAlign(config = config, fastq_folder = fastq_folder, use_parallel = use_parallel,  : 
  Forward_Reads_File has empty rows. Change fastqfiles parameter to 2, to operate only on reverse reads.
