185 **Cuffdiff Overview**
|
|
|
186
|
|
|
187 Cuffdiff is part of Cufflinks_. Cuffdiff find significant changes in transcript expression, splicing, and promoter use.

197 There is no such thing (yet) as an automated gearshift in expression analysis. It is all like stick-shift driving in San Francisco. In other words, running this tool with default parameters will probably not give you meaningful results. A way to deal with this is to **understand** the parameters by carefully reading the `documentation`__ and experimenting. Fortunately, Galaxy makes experimenting easy.

203 **Input format**
|
|
|
204
|
|
|
205 Cuffdiff takes Cufflinks or Cuffcompare GTF files as input along with two SAM files containing the fragment alignments for two or more samples.

209 **Outputs**
|
|
|
210
|
|
|
211 Cuffdiff produces many output files:
|
|
|
212
|
|
|
213 1. Transcript FPKM expression tracking.
|
|
|
214 2. Gene FPKM expression tracking; tracks the summed FPKM of transcripts sharing each gene_id
|
|
|
215 3. Primary transcript FPKM tracking; tracks the summed FPKM of transcripts sharing each tss_id
|
|
|
216 4. Coding sequence FPKM tracking; tracks the summed FPKM of transcripts sharing each p_id, independent of tss_id
|
|
|
217 5. Transcript differential FPKM.
|
|
|
218 6. Gene differential FPKM. Tests difference sin the summed FPKM of transcripts sharing each gene_id
|
|
|
219 7. Primary transcript differential FPKM. Tests difference sin the summed FPKM of transcripts sharing each tss_id
|
|
|
220 8. Coding sequence differential FPKM. Tests difference sin the summed FPKM of transcripts sharing each p_id independent of tss_id
|
|
|
221 9. Differential splicing tests: this tab delimited file lists, for each primary transcript, the amount of overloading detected among its isoforms, i.e. how much differential splicing exists between isoforms processed from a single primary transcript. Only primary transcripts from which two or more isoforms are spliced are listed in this file.
|
|
|
222 10. Differential promoter tests: this tab delimited file lists, for each gene, the amount of overloading detected among its primary transcripts, i.e. how much differential promoter use exists between samples. Only genes producing two or more distinct primary transcripts (i.e. multi-promoter genes) are listed here.
|
|
|
223 11. Differential CDS tests: this tab delimited file lists, for each gene, the amount of overloading detected among its coding sequences, i.e. how much differential CDS output exists between samples. Only genes producing two or more distinct CDS (i.e. multi-protein genes) are listed here.

227 **Settings**
|
|
|
228
|
|

229 All of the options have a default value. You can change any of them. Most of the options in Cuffdiff have been implemented here.

233 **Cuffdiff parameter list**
|
|
|
234
|
|
|
235 This is a list of implemented Cuffdiff options::
|
|
|
236
|
|
|
237 -m INT Average fragement length; default 200
|
|
|
238 -s INT Fragment legnth standard deviation; default 80
|
|
|
239 -c INT The minimum number of alignments in a locus for needed to conduct significance testing on changes in that locus observed between samples. If no testing is performed, changes in the locus are deemed not significant, and the locus' observed changes don't contribute to correction for multiple testing. The default is 1,000 fragment alignments (up to 2,000 paired reads).
|
|
|
240 --FDR FLOAT The allowed false discovery rate. The default is 0.05.
|
|
|
241 --num-importance-samples INT Sets the number of importance samples generated for each locus during abundance estimation. Default: 1000
|
|
|
242 --max-mle-iterations INT Sets the number of iterations allowed during maximum likelihood estimation of abundances. Default: 5000
|
|
|
243 -N With this option, Cufflinks excludes the contribution of the top 25 percent most highly expressed genes from the number of mapped fragments used in the FPKM denominator. This can improve robustness of differential expression calls for less abundant genes and transcripts.
