Hello,
I tried to generate a heatmap using qiime2 script
qiime feature-table heatmap
--i-table
--m-sample-metadata-file
--m-sample-metadata-column
--p-metric correlation
--p-method complete
--o-visualization
I got a Plugin error from feature-table:
Image size of 197193x557 pixels is too large. It must be less than 2^16 in each direction.
Please help me to fix the issue.
Hi @M_F,
This error indicates that your viz is too larger to be properly visualized. This may mean that you have a lot of features and plotting them as a heatmap would be huge.
My suggestion would be to collapse down (using qiime taxa collapse) to a taxonomic level of interest and re-run this command.
This will mean that you wont be able to look at ASV resolution differences but ASV differences might have been hard to interpret anyway because your study seems to have a lot of ASVs.
