To convert a pair of green and red IDAT files with raw Illumina intensities into a GTC file with genotype calls you need to provide both a BPM manifest file with the location of the probes and an EGT cluster file with the expected intensities of each genotype cluster. It is important to provide the correct BPM and EGT files otherwise the calling will fail possibly generating a GTC file with meaningless calls. Unfortunately newer IDAT files do not contain information about which BPM manifest file to use. The gtc2vcf bcftools plugin can be used to guess which files to use
path_to_idat_folder="..."
bcftools +gtc2vcf \
-i -g $path_to_idat_folder
This will generate a spreadsheet table with information about each IDAT file including a guess for what manifest and cluster files you should use. If a guess is not provided, contact the author for troubleshooting
Similarly, you can use the affy2vcf bcftools plugin to extract chip type information from CEL files
path_to_cel_folder="..."
bcftools +affy2vcf \
--cel --chps $path_to_cel_folder
The idat2gtc bcftools plugin can be used to convert Illumina IDAT files to GTC files
bpm_manifest_file="..."
egt_cluster_file="..."
bcftools +idat2gtc \
--bpm $bpm_manifest_file \
--egt $egt_cluster_file \
--idats $path_to_idat_folder \
--output $path_to_gtc_folder
The output is equivalent to the output of the Illumina GenCall algorithm while being significantly faster
If you do not have the manifest and cluster files for the Illumina IDAT files you are trying to convert, make sure to check the links [here][Illumina.md]
If you run the command with the option --autocall-date "" then the output should be deterministic and using the --preset option you can generate output equivalent to the output you obtain with any of the following:
- Illumina AutoConvert
- Illumina AutoConvert 2.0
- Illumina Array Analysis Platform Genotyping Command Line Interface
- Illumina Microarray Analytics Array Analysis Command Line Interface
If you similarly patch those tools to make them generate deterministic output, you should be able to verify that you get the same md5sum
Specifications for Illumina BPM, EGT, and GTC files were obtained through Illumina's BeadArrayFiles library and GTCtoVCF script. Specifications for IDAT files were obtained through Henrik Bengtsson's illuminaio package

bcftools sort -Ou -T ./bcftools. | \
bcftools norm --no-version -o $out_prefix.bcf -Ob -c x -f $ref --write-index
Heavy random access to the reference will be needed, so it is important that enough extra memory be available for the operating system to cache the reference or else the task can run excruciatingly slowly. Notice that the gtc2vcf bcftools plugin will drop unlocalized variants. The final VCF might contain duplicates. If this is an issue bcftools norm -d exact can be used to remove such variants. At least one of the BPM or the CSV manifest files has to be provided. Normalized intensities cannot be computed without the BPM manifest file. Indel alleles cannot be inferred and will be skipped without the CSV manifest file. Information about genotype cluster centers will be included in the VCF if the EGT cluster file is provided. You can use gtc2vcf to convert one GTC file at a time, but we strongly advise to convert multiple files at once as single sample VCF files will consume a lot of storage space. If you convert hundreds of GTC files at once, you can use the --adjust-clusters option which will recenter the genotype clusters rather than using those provided in the EGT cluster file and will compute less noisy LRR values. If you use the --adjust-clusters option and you are using the output for calling mosaic chromosomal alterations, then it is safe to turn the median BAF/LRR adjustments off during that step (i.e. use --adjust-BAF-LRR -1)
Optionally, between the conversion and the sorting step you can include a bcftools reheader --samples <file> command to assign new names to the samples where <file> contains old_name new_name\n pairs separated by whitespaces, each on a separate line, with old_name being the GTC file name without the .gtc extension in this case
When running the conversion, the gtc2vcf plugin will double check that the SNP manifest metadata information in the GTC file matches the descriptor file name in the BPM file to make sure you are using the correct manifest file. Sometimes, due to discrepancies between the BPM file name provided by Illumina and the internal descriptor file name, this safety check fails. To turn off this feature in these cases, you can use option --do-not-check-bpm
Affymetrix provides a best practice workflow for genotyping data generated using SNP6 and Axiom arrays. As an example, the following command will run the genotyping for the Affymetrix SNP6 array:
path_to_output_folder="..."
cel_list_file="..."
apt-probeset-genotype \
--analysis-files-path . \
--xml-file GenomeWideSNP_6.apt-probeset-genotype.AxiomGT1.xml \

--cel-files $cel_list_file \
--special-snps GenomeWideSNP_6.specialSNPs \
--chip-type GenomeWideEx_6 \
--chip-type GenomeWideSNP_6 \
--table-output false \
--cc-chp-output \
--write-models \
--read-models-brlmmp GenomeWideSNP_6.generic_prior.txt
Affymetrix provides Library and NetAffx Annotation files for their arrays (here, here, and here)
As an example, the following commands will obtain the files necessary to run the genotyping for the Affymetrix SNP6 array:
wget http://www.affymetrix.com/Auth/support/downloads/library_files/genomewidesnp6_libraryfile.zip
wget http://www.affymetrix.com/Auth/analysis/downloads/lf/genotyping/GenomeWideSNP_6/SNP6_supplemental_axiom_analysis_files.zip

unzip -o GenomeWideSNP_6.na35.annot.csv.zip GenomeWideSNP_6.na35.annot.csv
Note: If the program exits due to different chip types or probe counts with error message such as Wrong CEL ChipType: expecting: 'GenomeWideSNP_6' and #######.CEL is: 'GenomeWideEx_6' then make sure you included the option --chip-type GenomeWideEx_6 --chip-type GenomeWideSNP_6 or --force to the command line to solve the problem
The affy2vcf bcftools plugin can be used to convert Affymetrix CHP files to VCF

Heavy random access to the reference will be needed, so it is important that enough extra memory be available for the operating system to cache the reference or else the task can run excruciatingly slowly. The final VCF might contain duplicates. If this is an issue bcftools norm -d exact can be used to remove such variants. There is often no need to use the --adjust-clusters option for Affymetrix data as the cluster posteriors are already adjusted using the data processed by the genotype caller
Optionally, between the conversion and the sorting step you can include a bcftools reheader --samples <file> command to assign new names to the samples where <file> contains old_name new_name\n pairs separated by whitespaces, each on a separate line, with old_name being the CHP file name without the .chp extension
Illumina provides GRCh38/hg38 manifests for many of its genotyping arrays. However, if your genotyping array is not supported for the newer reference by Illumina, you can use the --fasta-flank and --sam-flank options to realign the flank sequences from the manifest files you have and recompute the marker positions. This approach uses flank sequence and strand information to identify the marker coordinates. It will need a sequence aligner such as bwa to realign the sequences and it seems to reproduce the coordinates provided from Illumina more than 99.9% of the times. Mapping information will follow the implicit dbSNP standard. Occasionally the flank sequence provided by Illumina is incorrect and it is impossible to recover the correct marker coordinate from the flank sequence alone
You first have to generate an alignment file for the flank sequences from a CSV manifest file
csv_manifest_file="..."
ref="$HOME/GRCh38/GCA_000001405.15_GRCh38_no_alt_analysis_set.fna" # or ref="$HOME/GRCh37/human_g1k_v37.fasta"
bam_alignment_file="..."
bcftools +gtc2vcf \
-c $csv_manifest_file \
--fasta-flank | \
bwa mem -M $ref - | \
samtools view -bS \
-o $bam_alignment_file
Notice that you need to use the -M option to mark shorter split hits as secondary and you should not sort the output BAM file as gtc2vcf expects it to have the sequences in the same order as in the CSV file . Then you load the alignment file while converting your GTC files to VCF including the -s $bam_alignment_file option
Some older manifest files from Illumina have thousands of markers with incorrect RefStrand annotations that will lead to incorrect genotypes. While Illumina has not explained why this is the case, it still distributes incorrect manifests. If you are using one of the following manifests
Human1M-Duov3_H
Human610-Quadv1_H
Human660W-Quad_v1_H
HumanCytoSNP-12v2-1_Anova
HumanOmni1-Quad_v1-0-Multi_H
HumanOmni1-Quad_v1-0_H
We advise to either contact Illumina to demand a fixed version or to use gtc2vcf to realign the flank sequences
Also, Illumina assigns chromosomal positions to indels by first left aligning the flank sequences in an incoherent way (see here). Apparently this is incoherent enough that Illumina also cannot get the coordinates of homopolymer indels right. For example, chromosome 13 ClinVar indel rs80359507 is assigned to position 32913838 in the manifest file for the GSA-24v2-0 array, but it is assigned to position 32913837 in the manifest file for GSA-24v3-0 array (GRCh37 coordinates). If you want to trust genotypes at homopolymer indels, we advise to use gtc2vcf to realign the flank sequences
The same functionality exists for the affy2vcf tool to convert Affymetrix data

To genotype raw Illumina IDAT intensity files using Illumina GenCall algorithms, Illumina over the course of the year has provided several command line interfaces written in the .NET language:
- AutoConvert (2011)
- AutoConvert 2.0) (2017)
- IAAP CLI (2019)
- Array Analysis CLI (2023)
We provide instructions to install and run these interfaces. The
sed -i -e ':a' -e 'N' -e '$!ba'installation commands are used to prevent the interfaces from timestamping the output GTC files by removing the System.DateTime calls and accesses to the CreationTime property from the binaries, with the goal of making each execution completely reproducible. AutoConvert 2.0, IAAP-CLI, and Array Analysis CLI binaries will both perform version 1.2.0 of the normalization step and seem to produce the exact same results while AutoConvert will only perform version 1.1.2 of the normalization step yielding somewhat different results. If you want to run these binaries but fail to download them, contact the author for troubleshooting
Illumina also provides the Beeline software for free and this includes the AutoConvert.exe command line executable which allows to call genotypes from raw intensity data using Illumina's proprietary GenCall algorithm. AutoConvert is almost entirely written in Mono/.Net language, except for one small mathmatical function (findClosestSitesToPointsAlongAxis) which is included within a Windows PE32+ library (MathRoutines.dll). As this is unmanaged code, to be run on Linux with Mono it needs to be embedded in an equivalent Linux ELF64 library (libMathRoutines.dll.so) as shown below. This function is run as part of the normalization of the raw intensities when sampling 400 candidate homozygotes before calling genotypes.
To run Illumina AutoConvert (version 1.6.3.1) you will need to fix the hardcoded Windows backlashes into UNIX [slashes](https://en.wikipedia.org/wiki/Slash_(punctuation), as shown below

To run Illumina AutoConvert 2.0 (version 2.0.1.179) you will need to separately download an additional Mono/.Net library (Heatmap.dll) from GenomeStudio or the polyploid clustering module and include it in your binary directory, most likely due to differences in which Mono and .Net resolve library dependencies, as shown below

Make sure that the IDAT files have the same name prefix as the IDAT folder name. The software might require up to 8GB of RAM to run. Illumina provides manifest (BPM) and cluster (EGT) files for their arrays here. Notice that if you provide the wrong BPM file, you will get an error such as: Normalization failed! Unable to normalize! and if you provide the wrong EGT file, you will get an error such as System.Exception: Unrecoverable Error...Exiting! Unable to find manifest entry ######## in the cluster file!

It is important to set the LANG environmental variable to en_US.UTF-8, if this is set to other values, due to a bug in iaap-cli causing malformed GTC files to be generated as a result. Due to another bug in iaap-cli, IDAT filenames cannot include more than two _ characters and should be formatted as BARCODE_POSITION_(Red|Grn).idat. When using iaap_cli you cannot process old array manifest files with loci data encoded as version 5 or older, such as HumanHap650Yv3_A.bpm, as the corresponding code was not carried over and you will get the error Error in reading file. Unknown Manifest version. The AutoConvert command line tool can read older manifest files. We change the autosomal call rate threshold to 0.0 both to more aggressively call gender in lower quality samples and to deal with an implementation issue that causes loci with null cluster scores to be included in the determination of the autosomal call rate threshold
