Off topic:Shapeit can't open existing file

Question

[Niek De Klein]

I am trying to run Shapeit -call function. However, it gives me the error chr_1.haps.gz is impossible to open, check file existence or reading permissions. I have set the file permissions completely open and checked that the file exists: ll chr_1.haps.gz -rwxrwxrwx 1 ndeklein group 8694707 Nov 24 10:40 chr_1.haps.gz. I also tried using the unzipped version of the file, but this gives the same error.

What am I doing wrong in the below command that it isn't able to open an existing file with full permissions?

shapeit  -call  \
         --input-gen genotype.beagle.genotype.probs.gg.gen.gz  \
                     genotype.chr1.beagle.genotype.probs.gg.gen.sample  
         --input-init hap.chr1.beagle.genotype.probs.gg.hap.gz \
                      sample.chr1.beagle.genotype.probs.gg.hap.sample \
         --input-map genetic_map_chr1_combined_b37.txt  \
         --input-scaffold chr_1.haps.gz \
