issues with reference list file

[rosave9]

Hi
I'm having issues running a reference list I downloaded from: enve-omics.ce.gatech.edu/data/fastani
(I downloaded the D1 dataset).

I open it and turn it into a .txt file and I see this when I open it in text edit:

gi|918757418|ref|NZ_CP011489.1| Actinobacteria bacterium IMCC26256, complete genome
AACGTGGGGCAATATGAGTTCTCCACAGAGCGCATCAAGGGCCCCTACCATGTTTTCAGGCTGGGGACAA
CCTCGCAAACTCGCTTAGTTAGCGGCTCTCCGAGGTTATCCACCGTTCGCTATTCGGGCGCTAGTTTGCT (......)
next genome
NUCLEOTIDE-SEQUENCE (...)
etc

Then I opened it in command and I see :

Acetobacter_ghanensis.LargeContigs.fna
Acetobacterium_woodii_DSM_1030.LargeContigs.fna
Acetobacter_pasteurianus_IFO_3283_01.LargeContigs.fna
Acetobacter_senegalensis.LargeContigs.fna
etc

So I tried a few things

1. I converted all .fna files into 1 single .txt file using
   cat *.fna >database.txt
   and tried running that .txt file as my --rf but that failed

2. I copied all the following genome names (see below) into 1 txt file and used that as my --rf but still failed
   Acetobacter_ghanensis.LargeContigs.fna
   Acetobacterium_woodii_DSM_1030.LargeContigs.fna
   Acetobacter_pasteurianus_IFO_3283_01.LargeContigs.fna
   Acetobacter_senegalensis.LargeContigs.fna
   and more...

3. To the file in Redirect ANI value to stdout #2 I included the path file so /nfs/turbo/lsi-NPDC/D1-folder/Acetobacter.. etc
   for each file and use that overall .txt file as my --rf and failed again

4. Tried using the D1.tar.gz original file as my --rf but that also failed

Could I see an example of a --rf file or could I get guidance on how to use a NCBI prokaryote ref genomes database downloaded into my own pipeline?
Thanks
