Deep-Atlas/pipeline/gene_to_nissl.py

Lines 115 to 119 in 1add677

	logger.warn(
	f"One of the gene slice has a section number ({section_number})"
	f"out of nissl volume shape {nissl_volume.shape}. This slice is"
	"removed from the pipeline."
	)

We should add extra spaces. I got this in the standard output

WARNING - gene-to-nissl - One of the gene slice has a section number (531.0)out of nissl volume shape (528, 320, 456). This slice isremoved from the pipeline.
