Error while generating heatmap

[Sidduppal]

Hey, I'm using phyloFlash_compare.pl to visualize the data generated using PhyloFlash. The script is able to generate barplot,matrix, and ntu_table but errors out when creating the heatmap. Do you think the error would be because of the massive data that I'm running (as mentioned in Issue#160) The log is attached. Command used: phyloFlash_compare.pl --csv T2R1_B_O.phyloFlash.NTUfull_abundance.csv,T4R1_B_O.phyloFlash.NTUfull_abundance.csv --task heatmap,barplot,matrix,ntu_table --out T2T4_phyloFlash_compare --log --barplot_rawval --keeptmp
