After fertilization but prior to the onset of zygotic transcription, the C. elegans zygote cleaves asymmetrically to create the anterior AB and posterior P1 blastomeres, each of which goes on to generate distinct cell lineages. To understand how patterns of RNA inheritance and abundance arise after this first asymmetric cell division, we pooled hand-dissected AB and P1 blastomeres and performed RNA-seq. http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE59943

For real projects I prefer the use of STAR.

To link sample info to info sequencing: Go to corresponding SRA page and save the information via the “Send to: File button” This file can also be used to make a script to download sequencing files from the web. Note that sra files can be converted to fastq files via the fastq-dump function of the sra-tools.

Download the Caenorhabditis_elegans.WBcel235.dna.toplevel.fa.gz from ensembl. Note that there is no info on multiple haplotypes so the primary assembly files are missing. So the info in toplevel file is the primary assembly.
