+# iVar container
+
+Main tool : [iVar](https://andersen-lab.github.io/ivar/html/manualpage.html)
+
+> iVar is a computational package that contains functions broadly useful for viral amplicon-based sequencing
+
+Additional tools (required):
+
+* [HTSlib](https://github.com/samtools/htslib) 1.20
+* [samtools](http://www.htslib.org/) 1.20
+
+## Example Usage
+
+```bash
+ivar trim -e -i {bam} -b {primer bed} -p {sample}.primertrim
+```
+
+```bash
+samtools mpileup -A -d 8000 -B -Q 0 --reference {reference.fasta} {bam} | \
+ ivar variants -p {sample}.variants -q 20 -t 0.6 -r {reference.fasta} -g {reference.gff}
+```
+
+```bash
+samtools mpileup -A -d 8000 -B -Q 0 --reference {reference.fasta} {bam} | \
+ ivar consensus -t 0.6 -p {sample}.consensus -n N
+```
+
+Starting with iVar version 1.4.1, the output of an aligner such as minimap2 and bwa (both included) can be piped into ivar trim directly
+```bash
+# index reference
+bwa index reference.fasta
+
+# run bwa and pipe into ivar (single line is split with \ for clarity)
+bwa mem reference.fasta read_1.fastq.gz read_2.fastq.gz | \
+ ivar trim -b primer.bed -x 3 -m 30 | \
+ samtools sort | \
+ samtools mpileup -aa -A -Q 0 -B -d 2000 - | \
+ ivar consensus -p output_prefix -m 10 -n N -t 0.5
+```
