I want a rule to perform realignment between normal and tumor. Here is another Snakefile that outputs h+2 (where h is the current hour of the day) to a file count. Since we have a wildcard in the rule, we can reuse the rule by simply. Wildcard values are yielded as the second tuple item. you can use snakemake. How to use list in Snakemake Tabular configuration, for describing of sequencing units for bioinformatic pipeline. I used recently introduced checkpoints to handle unknown output (see the scattering step below). So you're getting the error 'Wildcards' object has no attribute 'sample' because there are no wildcards for that rule. By replacing hardcoded variable names in input and output directives with wildcards, you can greatly reduce the amount of code needed, and have the pipeline work on new data, without. Example: Expected wildcard sample: 0053_P2017BB3S20R_S2, becomes: 0053_P2017BB3S20R_S2_R or 0053_P2017BB3S20R_S2_ depending on he rule.
