Any programs for analyzing solexa transcriptome (alternative splicing) ?

I wonder if Solexa reads, say 50bp can identify alternative splicing when you don't have a reference genome. How can we tell the alignment software to map the reads so we can find splice variant?
Alternative splicing has been reported using 454 reads. The longer reads is probably an advantage. Anyone has done similar work using Solexa reads?

i have reads.fq (5 000 000 reads RNA-seq) genome.fa
when i use bowtie align the reads, it aligns 4 200 000 reads.
but when i use tophat align the reads, the output file accepted_hits.sam only contains 1 900 000 reads. junctions.bed file is blank.

With a reference transcriptome, if you want to assign a quantity to each splicing variant I only know about this flux capacitor. Maybe not fully stable yet. I'm sure a lot of similar projects are in progress.
(Disclaimer: I personally know these people, they are friends of mine -but don't worry, contrary to me they still work in academic research).
Much more is expected to come from the RGASP project. I'd suggest to keep an eye on this.
Then, there are commercial products that claim to address "alternative splicing", but I am curious about what they really do...

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...-

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-
